a 60 cm-long, 3 cm-diameter aisi 1010 steel rod is welded to a furnace wall and passes through 20 cm of insulation before emerging into the surrounding air. the faurnace wall is at 300oc and the air temperature is 20oc. estimate the temperature of the bar tip if the heat transfer coefficient between the rod and air is taken to be 13 w/m2 k.

Answers

Answer 1

We may calculate the temperature of the bar tip using the boundary conditions and the one-dimensional heat conduction equation: q/A = -k(dT/dx).

Which of the following define the one-dimensional heat equation's boundary conditions?

Boundary circumstances: Particular actions at x0 = 0 and L: 1. Temperature constant: u(x0,t) = T for t > 0. 2. Insulated end: for t > 0, ux

Q = hA(T s - T air), where (x0,t) = 0

When we combine these equations, we obtain:

(T s - T air) = -(k/h)(dT/dx), where hA(T s - T air)/A = -k(dT/dx).

Assuming that the temperature gradient is constant over the length of the rod and integrating both sides from x = 0 to x = L, we arrive at:

(T s - 20) = -(43.5e-3 / 13)(T s - 300)*0.6 (T s - T air) = -(k/h)(T s - T furnace)*L

Simplifying:

(T s - 20) = -1.008(T s - 300)

T s - 20 = -1.008T s + 302.4 when expanded

When we solve for T s, we obtain T s = 1265.4 K.

Answers

Forging produces parts with equivalent strength, toughness, and ductility to hot chamber die casting. Forging is a manufacturing process in which metal is pressed or hammered into shape.

Forging is accomplished by applying high pressure to a metal piece in order to bend and shape it into the desired shape. The three main forging processes are Impression die forging; Cold forging, also known as a cold heading; Open-die forging. Impression dies forging. The forging method in which the metal is pounded or squeezed between two dies, typically the top and bottom are known as impression die forging. The material conforms to the form of the dies as a result of the process. Cold forging, also known as a cold heading. In the case of cold forging, also known as cold heading, the metal is hammered or squeezed under extreme pressure at room temperature. Cold forging is used to produce complex shapes in large numbers, including screws and bolts.

Open-die forging, also known as free forging, is the process of shaping metal between two flat dies. It's usually used to create simple shapes like cylinders and discs. The equivalent strength, toughness, and ductility of hot chamber die casting can be achieved with forging. The process of melting metal and forcing it into a die under high pressure is known as hot chamber die casting. This approach is ideal for producing a large number of small to medium-sized components with excellent precision and detail. Hot chamber dies casting is commonly used in the production of toys, car parts, and hardware because of its consistency and efficiency. In comparison to other manufacturing processes, hot chamber dies casting is quick, precise, and provides parts with excellent mechanical properties. Thus, from the above explanation, it is clear that forging produces parts with equivalent strength, toughness, and ductility to hot chamber die casting.

Answers

Answer:

When traveling at higher speeds (40 mph or faster), the most fuel-efficient way to keep the car cool is to follow these tips:

1. Use the vehicle's ventilation system: Instead of relying on air conditioning, use the car's ventilation system to circulate fresh air from outside. This helps to cool down the interior without putting extra load on the engine, thus saving fuel.

2. Close windows and sunroofs: To reduce wind resistance and drag, close all windows and sunroofs while driving at higher speeds. Open windows create drag, which can increase fuel consumption.

3. Park in the shade: Whenever possible, park your car in a shaded area to avoid excessive heating when it's not in use. This can help keep the car cooler and reduce the need for extra cooling when you start driving.

4. Use reflective sunshades or window tinting: Use reflective sunshades on your windshield and window tinting on side windows to reduce the amount of heat entering the car. This can help keep the interior cooler, reducing the need for excessive cooling while driving.

5. Maintain your vehicle: Regular maintenance, such as checking and replacing coolant, inspecting the radiator, and ensuring proper functioning of the engine cooling system, can help keep your car running efficiently and prevent overheating.

6. Plan your trips strategically: If possible, try to avoid driving during the hottest part of the day. By planning your trips to avoid peak temperatures, you can reduce the strain on your vehicle's cooling system and minimize the need for excessive cooling.

Remember that these tips are specifically focused on keeping the car cool while maintaining fuel efficiency at higher speeds. In certain circumstances, such as extremely hot weather, using the air conditioning sparingly may be necessary for passenger comfort, but it will increase fuel consumption.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

Explanation:

The predator uav has the following characteristics: has the following characteristics: wingspan = 14.85 m, wing area = 11.45 m2, maximum weight = 1020 kgf, and fuel weight = 295 kgf. the power plant is a rotax four-cylinder, four-stroke engine of 85 horsepower driving a two-blade, variable-pitch pusher propeller. assume that the oswald efficiency factor is 0.7, the zero-lift drag coefficient is 0.03, the propeller efficiency is 0.9, and the specific fuel consumption is 0.2 kgf of fuel per horsepower per hour. calculate the following:

1: maximum velocity at sea level.

2: the maximum range

3: the maximum endurance

Answers

Maximum Velocity:
The maximum velocity at sea level can be found using the following equation:

V_max = sqrt((2 * W) / (rho * S * CL_max))

where:

W = maximum weight = 1020 kgf
rho = air density at sea level = 1.225 kg/m^3
S = wing area = 11.45 m^2
CL_max = maximum lift coefficient = (2 * W) / (rho * V^2 * S)

To find CL_max, we need to assume a value for the velocity V and iterate until convergence. Let's start by assuming V = 70 m/s:

CL_max = (2 * 1020 kgf) / (1.225 kg/m^3 * (70 m/s)^2 * 11.45 m^2) = 1.87

Now we can use this value to find the maximum velocity:

V_max = sqrt((2 * 1020 kgf) / (1.225 kg/m^3 * 11.45 m^2 * 1.87)) = 35.5 m/s

Therefore, the maximum velocity of the Predator UAV at sea level is approximately 35.5 m/s.

Maximum Range:
The maximum range can be found using the following equation:

R = (L/D) * (1/OE) * ln(Wi/Wf)

where:

L/D = lift-to-drag ratio = CL / CD
CL = lift coefficient = W / (0.5 * rho * V^2 * S)
CD = drag coefficient = CD_0 + (CL^2 / (pi * e * AR))
CD_0 = zero-lift drag coefficient = 0.03
e = Oswald efficiency factor = 0.7
AR = aspect ratio = (wingspan)^2 / S
OE = overall efficiency = propeller efficiency * engine efficiency
propeller efficiency = 0.9
engine efficiency = 0.85 (assuming 85 horsepower for the engine)
Wi = initial weight = maximum weight + fuel weight = 1020 kgf + 295 kgf = 1315 kgf
Wf = final weight = maximum weight

We can start by assuming a value for the velocity V and iterating until convergence. Let's start with V = 25 m/s:

CL = 1315 kgf / (0.5 * 1.225 kg/m^3 * (25 m/s)^2 * 11.45 m^2) = 1.67
AR = (14.85 m)^2 / 11.45 m^2 = 19.3
CD = 0.03 + (1.67^2 / (pi * 0.7 * 19.3)) = 0.071
L/D = 1.67 / 0.071 = 23.5
OE = 0.9 * 0.85 = 0.765
R = 23.5 * (1/0.765) * ln(1315 kgf/1020 kgf) = 393 km

Now we can try a different value for V, let's say V = 30 m/s:

CL = 1315 kgf / (0.5 * 1.225 kg/m^3 * (30 m/s)^2 * 11.45 m^2) = 1.24
AR = (14.85 m)^2 / 11.45

Determine the enthalpy, volume and density of 1.0 kg of steam at a pressure of 0.5 MN/m2 and with a dryness fraction of 0.96

Answers

Answer:

Enthalpy, hsteam = 2663.7 kJ/kg

Volume, Vsteam = 0.3598613 m^3 / kg

Density = 2.67 kg/ m^3

Explanation:

Mass of steam, m = 1 kg

Pressure of the steam, P = 0.5 MN/m^2

Dryness fraction, x = 0.96

At P = 0.5 MPa:

Tsat = 151.831°C

Vf = 0.00109255 m^3 / kg

Vg = 0.37481 m^3 / kg

hf = 640.09 kJ/kg

hg = 2748.1 kJ/kg

hfg = 2108 kJ/kg

The enthalpy can be given by the formula:

hsteam = hf + x * hfg

hsteam = 640.09 + ( 0.96 * 2108)

hsteam = 2663.7 kJ/kg

The volume of the steam can be given as:

Vsteam = Vf + x(Vg - Vf)

Vsteam = 0.00109255 + 0.96(0.37481 - 640.09)

Vsteam = 0.3598613 m^3 / kg

From the steam table, the density of the steam at a pressure of 0.5 MPa is 2.67 kg/ m^3

Advise a suitable structural form for the 50-storey residential
towers to resist strong lateral wind load.

Answers

A suitable structural form for the 50-storey residential towers to resist strong lateral wind loads is a reinforced concrete shear wall system. This system involves the use of vertical concrete walls distributed throughout the building's floor plan. These walls act as the primary structural elements that resist the lateral forces generated by strong winds.

The reinforced concrete shear wall system offers several advantages in terms of lateral stability and wind load resistance. The vertical walls provide stiffness and strength to counteract the lateral forces, effectively reducing the building's sway and minimizing the potential for structural damage. The system also offers good structural integrity, durability, and fire resistance.

In addition to the shear walls, other complementary structural elements such as floor diaphragms, columns, and foundation systems are incorporated to ensure overall stability and load distribution. Proper structural analysis and design, including consideration of wind load effects and local building codes, are crucial to ensure the towers can withstand the anticipated wind forces.

It is important to note that structural design considerations should involve the expertise of professional structural engineers who will assess the specific site conditions, wind loads, and architectural requirements to determine the most appropriate structural form for the 50-storey residential towers.

Answers

Answer:

B) Minimum voltage drop across meter

Explanation:

An ammeter is a measuring instrument device that is used to measure small currents flowing through a circuit in milli-ampere. The internal resistance of the milli ammeter is very low so that there would be a minimum voltage drop across the meter causing a minimum effect of the current in the circuit, this results to a measurement closer to the original value. If a high resistance is place, there would be large voltage drop therefore the current measured would be lesser than the original value.
