Steam flows through a copper pipe (kc=150Wm∙K⁄) that has an inner diameter of 19 mm and an outer diameter of 21 mm. The convection coefficient between the 200°C steam and the pipe is 200Wm2∙K⁄. The pipe is wrapped with insulation (ki=0.03Wm∙K⁄) so that the outer surface of the insulation is safe to touch. If the inner surface of the pipe is at 180°C: a) What is the temperature of the outer surface of the pipe for unit length of the pipe (or the inner surface of the insulation)? b) What is the thickness of the insulation so that the temperature is 40°C at the outer surface of the insulation? (Note: Assume negligible contact resistance)
Answers
Answer:
a) The temperature on the outer surface of the pipe is approximately 179.97 °C
b) The thickness of the insulation is approximately 0.857 m
Explanation:
We have;
\(\dfrac{1}{U} = \dfrac{1}{\alpha _A}\)
αA = 200 W/(m²·K)
\(\dot q\) = (T₂ - T₁) × U
\(\dot q\) = (200 - 180) × 200 = 4,000
For the pipe, we have;
\(\dfrac{1}{U} =\dfrac{x}{kc }\)
\(\dot q\)/U= (T₂ - T₁)
∴ 4000×\(\dfrac{0.001}{150}\) = (180 - T₂)
T₂ ≈ 179.97 °C
The temperature on the outer surface of the pipe, T₂ ≈ 179.97 °C
b) For the insulation, we have;
\(\dfrac{1}{U} = \dfrac{x}{ki } = \dfrac{x}{0.03}\)
T₂ - T₃ = 179.97 °C - 40°C ≈ 139.97°C
\(\dot q\)/U= (T₂ - T₃)
\(x = \dfrac{\dot q \cdot kc}{T_2 - T_3} = \dfrac{4,000 \times 0.03}{139.97} \approx 0.857\)
The thickness of the insulation, x ≈ 0.857 m

A driver is traveling at 90 km/h down a 3% grade on good, wet pavement. An accident
investigation team noted that braking skid marks started 75m before a parked car was
hit at an estimated 45 km/h. Ignoring air resistance, calculate the theoretical friction
coefficient.
Answers
Answer:
0.35
Explanation:
We resolve the component of the weight of the car along and perpendicular to the grade. We have mgsinФ and mgcosФ where Ф = angle of grade.
Now, the frictional force f = μN = μmgcosФ where μ = coefficient of friction
So, the net force along the grade is F = mgsinФ - μmgcosФ.
The work done by this force moving a distance, d along the grade is
W = (mgsinФ - μmgcosФ)d
This work equals the change in kinetic energy of the car. So ΔK = 1/2m(v₂² - v₁²) = W = (mgsinФ - μmgcosФ)d
1/2m(v₂² - v₁²) = (mgsinФ - μmgcosФ)d
1/2(v₂² - v₁²) = (gsinФ - μgcosФ)d
(v₂² - v₁²)/2d = (gsinФ - μgcosФ)
dividing through by gcosФ, we have
(v₂² - v₁²)/2dgcosФ = (gsinФ/gcosФ) - μgcosФ/gcosФ
(v₂² - v₁²)/2dgcosФ = tanФ - μ
μ = tanФ - (v₂² - v₁²)/2dgcosФ
given that tanФ = 3% = 3/100 and 1 + tan²Ф = 1/cos²Ф, cosФ = 1/(√1 + tan²Ф) = 1/(√1 + (3/100)²) = 1/(√1 + (9/10000)) = 1/(√10000 + 9/10000) = 1/√(10009/10000) = 100/√10009 = 100/100.05 = 0.9995.
Also, given that v₁ = 90 km/h = 90 × 1000/3600 m/s = 25 m/s and v₂ = 45 km/h = 45 × 1000/3600 m/s = 12.5 m/s, d = 75 m and g = 9.8 m/s².
So, substituting the values of the variables into the equation, we have
μ = tanФ - (v₂² - v₁²)/2dgcosФ
μ = 3/100 - ((12.5 m/s)² - (25 m/s)²)/(2 × 75 m × 9.8 m/s² × 0.9995)
μ = 3/100 - ((156.25 m/s)² - (625 m/s)²)/1,469.265 m²/s²
μ = 3/100 - (-468.75 m²/s²)/1,469.265 m²/s²
μ = 3/100 + 468.75 m²/s²/1,469.265 m²/s²
μ = 0.03 + 0.32
μ = 0.35
So, theoretical friction coefficient is 0.35

Therefore, this model of design is just based on the yield capacity of the steel.
• What is Strain? . What is the strain gauge? What is the principle of strain gauge (tension and compression)? • The uses of each type of strain gauge? • Include pictures for reference.
Answers
Strain is a unitless measurement that refers to the amount of deformation of an object as a result of an applied force or stress. The strain gauge is an electrical device that measures strain by detecting changes in electrical resistance. It is made up of a thin metal foil or wire that is bonded to a backing material, such as paper or plastic.
The principle of strain gauge is based on the fact that when a metal conductor is stretched, its resistance increases, and when it is compressed, its resistance decreases. The resistance change is proportional to the amount of strain that the gauge is exposed to. Therefore, by measuring the change in resistance, we can determine the amount of strain that the object has undergone. Strain gauges can be used to measure both tension and compression. When the strain gauge is under tension, the metal foil is stretched, causing it to become longer and thinner. This increases the resistance of the gauge. When the gauge is under compression, the metal foil is compressed, causing it to become shorter and thicker.
This decreases the resistance of the gauge.There are several types of strain gauges, each with its own unique application. Here are a few examples:• Linear strain gauges - used to measure uniaxial strain in one direction.• Rosette strain gauges - used to measure biaxial or triaxial strain in multiple directions.• Weldable strain gauges - designed to be welded directly to a metal surface.• Bolt-on strain gauges - attached to the surface of a bolt or other fastener to measure the strain on the joint.• Strain gauge load cells - used to measure force, weight, or torque.

Problem No. 3: Constant Rate Filtration (8 pt)
Assuming the same filter as in Problem No.2 (with the same cake and filter medium) is used for filtration of an aqueous suspension, but desired for working at a constant filtration rate of 200 L/h.
=> What pressure drop (ΔP) would be attained after 45 min from the start ?
Answers
The actual filtration rate (dV/dt) for a time interval of 45 minutes is given by the formula: dV/dt = Q/A = (300 L / 45 min) / A = 6.67 L/min.
How is constant pressure filtration calculated?Constant rate filtration is described by the equation P = av c A 2 (V) d V d t + R m A d V d t. If the average specific resistance and dry cake mass per unit volume of filtrate are constant, i.e. for incompressible filtration, then Eq. (5) should be linear. In Eq. 1, the "filtration constants"
300 L of filtrate were collected after 45 minutes.
The following calculation can be used to calculate the actual filtration rate (dV/dt):
\(dV/dt = A * (dh/dt)\)
(dV/dt) = Q/A
where Q represents the filtrate's volumetric flow rate.
As a result, the real filtration rate (dV/dt) at 45 minutes is:
dV/dt = Q/A = (300 L / 45 min) / A = (6.67 L/min) / A

Apply Gauss-Jordan elimination to find the inverse of a matrix.
How to find the inverse of a matrix using the Gauss-Jordan elimination method?The closed-loop transfer function can be obtained by multiplying the system's transfer function with the PID controller. The closed-loop poles are the roots of the denominator polynomial of the closed-loop transfer function.
a) To obtain the closed-loop transfer function analytically, you need to consider the transfer function of the system (given in the figure) and the transfer function of the PID controller. Multiply these two transfer functions and simplify the expression to obtain the closed-loop transfer function.

The current that passes through the residual heater is 4.94 Ampere.
How to calculate the current passes from the residual heater?Given,
Volume = 0.3 m³
Pressure = 200 kPa
Temperature = 27°C
Voltage = 110 V
Time = 10 minutes
According to the ideal gas equation,
m = PV/RT = 200×10³×0.3/(189×(27+273)) = 1.058 kg
V₁/T₁ = V₂/T₂
T₂ = (V₂/V₂)×T₁ = 2×(27+273) = 600 K = 600 - 273 = 327°C
W = P(V₂ - V₁) = 200×10³ ×(2×0.3 - 0.3) = 60 kJ
Q - W = mCp(T₂ - T₁)
Q - 60 = 1.058×0.839×(327-27)
Q = 326.3 kJ
V×I×t = 326.3 kJ
110×I×(10×60) = 326.3×10³

The mass of air in the tank is 0.05597 kg.
What is the mass of air, in kg, in the tank?Given data:
Volume of air (V) = 2 m³
Temperature (T) = -93°C = -93 + 273.15 = 180.15 K
Gage pressure (P) = 1.4 MPa = 1.4 * 10⁶ Pa
To determine the mass of air, we can use the ideal gas law equation \(PV = nRT\)

The steel shaft has a diameter of 40 mm and is fixed at its ends A and B . If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa.
Q6/
Answers
Answer:
See explanation.
Explanation:
Since no figure was given I solved a problem that was similar to the one you described that I worked in my mechanics of materials class. The method should be very similar for your figure. See attached image for my work.
If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.
What we need to perform?We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,
P=2×pi×N×T/60 or T=60×p/2×pi×N
Where P=power transmitted by the shaft=50×10³W
N=rotation speed of the shaft in rpm=730rpm
Pi=3.142
T is the twisting moment
By substituting the values for pi, N and P, we get
T=654Nm or 654×10³Nmm
Also, T=pi×rho×d³/16 or rho=16×T/pi×d³
Where rho=maximum shear stress
T = twisting moment=654×10³Nmm
d= diameter of shaft= 40mm
By substituting T, pi and d
Rho=52Mpa
b. For a hollow shaft, the value for rho is unknown
T=pi×rho(do⁴-di⁴/do)/16
Rho=T×16×do/pi×(do⁴-di⁴)
Where
T= twisting moment=654×10³Nmm gotten above
do=outside shaft diawter=40mm
di= inside shaft diameter =30mm
Pi=3.142
Substituting values for pi, do, di and T.
Rho=76Mpa
Therefore, If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

Stairs, ladders, or ramps are required at an elevation break of 19 inches or more.
This is to ensure the safety of those who use the facility, particularly people with disabilities. If there is a level change of more than 19 inches, it is suggested that a ramp or elevator be installed to make it more accessible. Ramps, ladders, and stairs are vital components of any building or construction that has an elevation break of 19 inches or more. Their function is to offer a secure and convenient way of accessing various floors within a facility, whether it's a residential or commercial structure.
The Americans with Disabilities Act (ADA) has laws that ensure that facilities are built to be accessible to individuals with disabilities. For instance, they provide guidelines on the minimum width of a ramp or the steepness of the stairs. This is to ensure that individuals who use a wheelchair or walker can easily navigate the building. If a building has an elevation break of more than 19 inches, then it is required to have a ramp that meets the guidelines of the ADA. This will make it easier for individuals with disabilities to move from one floor to the next.
Moreover, if the building is relatively large and has multiple floors, an elevator is recommended. The elevator will ensure that people with disabilities can quickly move around the building without any issues. In conclusion, stairs, ladders, or ramps are required at an elevation break of 19 inches or more. The ADA guidelines ensure that individuals with disabilities have access to all parts of the building. They stipulate the minimum width, height, and slope of a ramp, as well as the steepness of the stairs. When designing a building, it is crucial to consider these guidelines to make the facility accessible to all.
