A plastic panel area A= 1 ft2 and thickness X=0.252 inches was found to conduct heat at a rate of 3.0 W at steady state with temperatures To = 24.00oC and T1 = 26.00oC imposed on the two main surfaces. What is the thermal conductivity of the plastic in cal/cm-s-K at 25oC.
A steady-state electric motor operates under 10 Ampere and 220 Volt operating conditions. The output shaft rotates with 100 rpm (rpm) and 16 Nm torque. The heat transfer from the electric motor to the environment is related to the equation of surface temperature Tb, ambient temperature T0 and hA(Tb-T0). The energy transfer is shown on the figure with the help of arrows. (h=100 W/(m2K)), A= 0.195 m2, T0= 293 K) a) Determine the temperature Tb in K (Kelvin). b) Assuming the electric motor as the system, determine the entropy production in kW/K. c) Assume the area of the system boundary as the ambient temperature (T0) and determine the entropy generation in kW/K for the extended system boundaries.

Q1/ Consider a large plane wall of thickness L=0.03 m. The wall surface at x =0 is insulated, while the surface at x =L is maintained at a temperature of 30°C. The thermal conductivity of the wall is k=25 W/m °C, and heat is generated in the wall at a rate of g = 9oe0.5x/L W/m³ Where g, = 8 x 10 W /m². Assuming steady one-dimensional heat transfer, (a) express the differential equation and the boundary conditions for heat conduction through the wall, (b) obtain a relation for the variation of temperature in the wall by solving the differential equation, and (c) determine the temperature of the insulated surface of the wall.

(Q4) A 4m x 6m wall consists of 4 glass windows of 2m x 1.5m dimensions. The wall has thickness of 0.13m and a thermal conductivity of 0.5 W/m.K, while the glass windows are 6 mm thick with a thermal conductivity of 1.228 W/m.K. The values of intemal and external surface conductance for the wall (including glass) are 7.8 W/m? K and 34.4 W/m².K, respectively. The intemal and extemal temperatures are 22° C and 42°C, respectively. Calculate the total heat transfer rate through the wall. What percentage of this heat transfer is through the windows?

Heat Transfer question In order to cool down a hot steel sphere (its diameter is 5 cm), CO2 gas is blown over it through a pipe with a diameter of 10 cm. The CO2 gas is kept at atmospheric pressure while moving through a smooth pipe at a speed of 6 m/sec. The gas temperature entering the pipe is 300K and exiting the pipe is 340 K. The pipe temperature at the entrance is 350K and at the exit is 550K. The sphere is located just about the pipe exit. Find the convective heat transfer coefficient of the gas moving in the pipe, the heat transfer rate at the pipe and the pipe length. What is the surface temperature of the sphere if the heat transfer rate between the sphere and the gas is 7W and its surface temperature is higher than the gas?
1. Humans are able to control their rates of heat production and heat loss to maintain a nearly constant core temperature of Te = 37°C under a wide range of environmental conditions. This process is called thermoregulation. From the perspective of calculating heat transfer between a human body and its surroundings, we focus on a layer of skin: fat, with its outer surface exposed to the environment and its inner surface at a temperature slightly less than the core temperature, T = 35°C = 308 K. Consider a person with a skin/fat layer of thickness L = mm and effective thermal conductivity k = 0.3 "- The person has a surface area A = 1.8 m? and is dressed in a bathing suit. The m· K emissivity of the skin is ɛ = 0.95. a). When the person is in still air at T = 282 K, what is the skin surface temperature and rate of heat loss to the environment? Convection heat transfer to the air is characterized by a free convection coefficient of h 2 m2 -K b). When the person is in water at T = 282,…
A hot fluid (60° C) flows inside an copper tube with 1.7 cm OD and 1.5 cm ID. The inside of the pipe has a heat transfer coefficient of 130 W/m2-K. The tube is exposed to a room with air and surrounding walls of 23° C. The heat transfer coefficent between the outside of the walls and the room air is 15 W/m2 K. Draw an equivalent circuit diagram of the heat transfer, and quantify the resistance to heat flow by each of the two convective processes, conduction in the tube, and radiation between the outside of the tube and the room walls. Are any of the resistances negligible to the overall heat transfer, and if so, which ones?
I also need the diagram of given, equations, and assumptions.
