Explanation:

Answer:

Hello your question is incomplete attached below is the complete question

answer :

a) 95.80°C

b) 8.23 MW

Explanation:

Convection heat transfer coefficient = 860 W/m^2 . k

a) Calculate for the temp of sheet metal when it leaves the oil bath

first step : find the Biot number

Bi = hLc / K  ------- ( 1 )

where : h = 860 W/m^2 , Lc = 0.0025 m ,  K = 60.5 W/m°C

Input values into equation 1 above

Bi = 0.036 which is < 1  ( hence lumped parameter analysis can be applied )

next : find the time constant

t ( time constant ) = h / P*Cp *Lc  --------- ( 2 )

where : p = 7854 kg/m^3 , Lc = 0.0025 m , h = 860 W/m^2, Cp = 434 J/kg°C

Input values into equation 2 above

t ( time constant ) = 0.10092 s^-1

Determine the elapsed time

T = L / V = 9/20 = 0.45 min

∴   temp of sheet metal when it leaves the oil bath

= (T(t) - 45 ) / (820 - 45)  = e^-(0.10092 * 27 )

T∞ =  45°C

Ti = 820°C

hence : T(t) = 95.80°C

b) Calculate the required rate of heat removal form the oil

Q = mCp ( Ti - T(t) ) ------------ ( 3 )

m = ( 7854 *2 * 0.005 * 20 ) = 26.173 kg/s

Cp = 434 J/kg°C

Ti =  820°C

T(t) = 95.80°C

Input values into equation 3 above

Q = 8.23 MW

Given parameters for Maxwell's capacitance bridge are as follows:R2=400Ω; R3=600Ω; R4=1000Ω; C4=0.5μF.The formula for calculating R1 and L1 in the given Maxwell's capacitance bridge is, R1 = (R2R3)/R4L1 = 1/(4π²C4R3²)The value of R1 is calculated as follows;R1 = (R2R3)/R4 = (400 x 600)/1000 = 240 Ω.

The value of L1 is calculated as follows;L1 = 1/(4π²C4R3²) = 1/(4π² x 0.5 x 10^-6 x 600²) = 2.213 mHNow, let's calculate the quality factor, Q factor of coil. The formula to calculate the quality factor is given as,Q = 2πfL/RHere, f is the frequency of the signal, L is the inductance and R is the equivalent series resistance (ESR) of the coil.

The value of frequency is given as 1000Hz. We have calculated the value of L1 as 2.213 mH.The equivalent series resistance (ESR) of the coil is the resistance of the coil when it is measured by a device that passes an AC current through it. Let's say that the equivalent series resistance of the coil is Rcoil.

Hence,Q = 2πfL1/RcoilQ = 2π x 1000 x 2.213 x 10^-3/RcoilQ = 14.01/Rcoil.

As the flow rate increases, the extension rate also increases. This is because the flow rate determines the amount of force applied to the material, which in turn causes the material to extend or stretch. Therefore, a higher flow rate will result in a higher extension rate.

When a material is subjected to a flow or shear stress, it begins to deform or stretch, which is referred to as extension. The rate at which this extension occurs depends on several factors, including the flow rate or the rate at which the stress is applied.

As the flow rate increases, the amount of force applied to the material increases, resulting in a higher extension rate. This is because the material experiences more stress, causing its molecules to rearrange and elongate, resulting in an increased extension rate. The extension rate may continue to increase with the flow rate up to a certain point, beyond which further increases in flow rate may not lead to significant increases in extension rate.

It's important to note that the relationship between flow rate and extension rate can vary depending on the material being tested, as well as other factors such as temperature, pressure, and the presence of impurities. Understanding the relationship between flow rate and extension rate is important in various fields, including materials science, engineering, and manufacturing, where the mechanical properties of materials are critical for their successful use.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity.

Closing the throttle, turning off the fuel pump, setting the mixture control to idle cutoff, and simply cranking the engine is the most reliable hot start method I've found.

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity. If you are unable to climb, close both throttles and land straight ahead.

The typical practice for the majority of aircraft would be to abandon takeoff if an engine failed during takeoff. In small aircraft, the pilot should turn the throttles down to idle, activate the speed brakes (if provided), and apply the brakes as needed if the engine fails before VR (Rotation Speed).

Correct question is;

A commercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at −30°C by rejecting its waste heat to cooling water that enters the condenser at 18°C at a rate of 0.25 kg/s and leaves at 26°C. The refrigerant enters the condenser at 1.2 MPa and 65°C and leaves at 42°C. The inlet state of the compressor is 60 kPa and −34°C and the compressor is estimated to gain a net heat of 450 W from the surroundings. Determine (a) the quality of the refrigerant at the evaporator inlet, (b) the mass flow rate of the refrigerant.

Answer:

A) Quality = 0.48

B) Mass flow rate; m' = 0.0455 kg/s

Explanation:

A) From the refrigerant R-144 table I attached,

At P=60kpa and interpolating at - 34°C,we obtain enthalpy;

h1 = 230.03 Kj/kg

Also at P= 1.2MPa which is 1200kpa and interpolating at 65°C,we obtain enthalpy ;

h2 = 295.16 Kj/Kg

Also at P= 1.2MPa which is 1200kpa and interpolating at 42°C,we obtain enthalpy ;

h3 = 111.23 Kj/Kg

h4 is equal to h3 and thus h4 = 111.23 Kj/kg

We want to find the refrigerant quality at the evaporation inlet which is state 4 and P= 60 Kpa.

Thus, from the table attached, we see that hf = 3.84 at that pressure and hg = 227.8

Now, to find the quality of the refrigerant, we'll use the formula,

x4 = (h4 - hg) /(hf - hg)

Where x4 is the quality of the refrigerant. Thus;

x4 = (111.23 - 3.84)/(227.8 - 3.84) = 0.48

B) The mass flow rate of the refrigerant can be determined by applying a 1st law energy balance across the condenser. Thus, the water properties can be obtained by using a saturated liquid at the given temperatures;

So using the first table in the image i attached; interpolating at 18°C; hw1 = hf = 75.54 kJ/kg

Also interpolating at 26°C; hw2 = hf = 109.01 kJ/kg

Now;

(m')(h2 − h3)= (m_w)(hw2 − hw1)

m' is mass flow rate

Making m' the subject, we get;

m' = [(m_w)(hw2 − hw1)]/(h2 − h3)

m' = [(0.25 kg/s)(109.01 − 75.54) kJ/kg] /(295.13 − 111.37) kJ/kg

m' = 8.3675/183.76

m' = 0.0455 kg/s

Explanation:

It does not seem reasonable to expect a tensile stress of 200 MPa to produce a reduction in specimen diameter of 0.08 mm

Given data :

Diameter ( d ) = 10 mm

length ( l ) = 150 mm

elasticity ( ∈ ) = 100 GPa

longitudinal strain ( б ) 200 MPa

Poisson ratio ( μ )  ( assumed ) =0.3

Assumption : deformation totally elastic

attached below is the detailed solution to why it is not reasonable .

The Sd value = 0.08 > the calculated Sd value ( 6*10^-3 ) hence it is not reasonable to expect a tensile stress of 200 MPa to produce a reduction in specimen

The maximum capillary rise and tube diameter for this maximum-rise case will be d=0.414× 10⁻⁴ m.

What do you mean by tube?

A tube, also known as tubing, is a long hollow cylinder that is used to transport fluids (liquids or gases) or to protect electrical and optical cables and wires.

Given that, P = 4 KPa

Contact angle = 6°

Surface tension = 1 N/m

Lets assume that atmospheric pressure = 100 KPa

Lets take that density of water = 1000kg/m³

So the capillarity rise h

h=ΔP/ρg

h= (100×1000-4×1000)/(1000×10)

h= 9.61 m

We know that for capillarity rise h

h=2σcosθ/rρg

r = 2σcosθ/hρg

r = (2×1cos4°)/(9.61×1000×10)

r = 0.207×10⁻⁴m

The theoretical maximum transfer rate over the PSTN using 8 levels per signaling element and a bandwidth of 3000 Hz is 3 bits per second.

The theoretical maximum transfer rate over a Public Switched Telephone Network (PSTN) using 8 levels per signaling element and a bandwidth of 3000 Hz can be deduced as follows:

The number of bits that can be transmitted per signaling element can be calculated using the formula:

Bits per signaling element = log2 (Number of levels)

In this case, we have 8 levels per signaling element, so the bits per signaling element would be:

Bits per signaling element = log2 (8) = 3

Since there are 3000 Hz of bandwidth available, the number of signaling elements per second can be calculated by dividing the bandwidth by the number of Hz per signaling element:

Signaling elements per second = Bandwidth / Hz per signaling element

Hz per signaling element = 3000 Hz / 1 signaling element = 3000 Hz

Now we can calculate the theoretical maximum transfer rate:

Transfer rate = Signaling elements per second × Bits per signaling element

Transfer rate = (3000 Hz / 3000 Hz) × 3 bits = 3 bits per second

Therefore, the theoretical maximum transfer rate over the PSTN using 8 levels per signaling element and a bandwidth of 3000 Hz is 3 bits per second.

In summary, the **theoretical maximum transfer rate** in this scenario is **3 bits per second**. This calculation is based on the given parameters of 8 levels per signaling element and a bandwidth of 3000 Hz. By utilizing logarithmic calculations and dividing the available bandwidth by the Hz per signaling element, we can determine the number of signaling elements per second. Finally, multiplying the signaling elements per second by the bits per signaling element gives us the maximum transfer rate.

Answer:

The mass of fuel added, which is 10,166.2 kg is less than 22,300 kg which is the mass of fuel required to travel from Toronto to Edmonton, the plane therefore crashed.

Explanation:

Since density ρ = m/v where m = mass of fuel and v = volume of fuel, we need to find the mass of each volume of fuel.

So, m = ρv now ρ = specific gravity × density of water = 0.803 × 1000 kg/m³ = 803 kg/m³.

To find the mass of the 7,682 L of fuel, its volume is 7,682 dm³ = 7,682 dm³ × 1 m³/1000 dm³ = 7.682 m³.

It's mass, m = 803 kg/m³ × 7.682 m³ = 6168.646 kg

To find the mass of the extra 4,916 L of fuel added, we have

m' = ρv' where v' = 4,916 L = 4,916 dm³ = 4916 dm³ × 1 m³/1000 dm³ = 4.916 m³

m' =  803 kg/m³ × 4.916 m³ = 3947.548 kg

So, the total mass of the fuel is m" = m + m' = 6168.646 kg + 3947.548 kg = 10116.194 kg ≅ 10,166.2 kg

Since this mass of fuel added, which is 10,166.2 kg is less than 22,300 kg which is the mass of fuel required to travel from Toronto to Edmonton, the plane therefore crashed.

The principal of the loan that TMI Systems repaid was $90,000.

The formula to calculate the principal of a loan is P = L + I, where P is the principal, L is the loan amount, and I is the total interest paid over the duration of the loan.

In this case, we are given that the loan amount was 10% per year simple interest, which can be calculated by multiplying the principal by the interest rate (0.1) and the duration of the loan (5 years). Therefore, the total interest paid over the duration of the loan is P x 0.1 x 5 = $50,000.

We are also given the total amount repaid, which is the sum of the principal and the total interest paid. Therefore, we can calculate the principal by subtracting the total interest paid from the total amount repaid.

This gives us $140,000 - $50,000 = $90,000. As the principal must be a positive value, the principal of the loan is $90,000.

According to the textbook, another way to look at social control theory is to call it "social bond theory".

Social control theory, also known as social bond theory, suggests that people's behavior is influenced by the strength of their social bonds or connections with society. This theory posits that individuals who have strong social bonds are less likely to engage in criminal behavior as they have more to lose from being caught and punished. Conversely, individuals who have weak social bonds are more likely to engage in deviant behavior as they have less to lose.

Social control theory argues that it is the strength of social bonds, rather than external factors such as poverty or peer pressure, that primarily influences individual behavior. Thus, social control theory offers a unique perspective on the causes of criminal behavior and the mechanisms that can prevent it.

The formula to calculate the cycle time is Cycle time = Load time + Haul time + Dump time + Return time. For the given situation, the load time and dump time are given in Table 9.8.

Table 9.8 provides cycle times for a variety of construction equipment, including wheeled loaders of different capacities.

The problem describes a specific situation where a 4.75 cy (cubic yard) wheeled loader is moving poor blasted rock to a site 100 feet away. The loader will be traveling at its maximum speed in first gear, and the problem asks for the cycle time, including haul and return times.

To calculate the cycle time, we can use the formula:

Cycle time = Load time + Haul time + Dump time + Return time

From Table 9.8, we can see that the load time for a 4.75 cy wheeled loader is 0.10 min (6 seconds), and the dump time is 0.05 min (3 seconds).

Assuming that the loader is loaded and dumped instantaneously, we only need to calculate the haul and return times.

To calculate the haul time, we can use the formula:

Haul time = Distance / Speed

The distance in this case is 100 feet, and the maximum speed of the loader in first gear is given in Table 9.8 as 4.0 mph. Converting feet to miles and using the formula, we get:

Haul time = 100 / (4.0 ˣ 5280/60) = 0.0227 min (1.36 seconds)

To calculate the return time, we can assume that it is equal to the haul time, since the loader is traveling at its maximum speed in both directions.

Therefore, the return time is also 0.0227 min (1.36 seconds).

Adding all of the times together, we get:

Cycle time = 0.10 + 0.0227 + 0.05 + 0.0227 = 0.1954 min (11.7 seconds)
