A 15 cm outer diameter steam pipe is covered with 5 cm of high temperature insulation (K = 0.85 W/mk) and 4 cm of low temperature insulation (K = 0.72 W/mK). The steam is at 500°C and ambient air is at 40°C. Neglecting thermal resistances of steam and air sides and metal wall, calculate the heat loss from 1000 m length of the pipe.

3.10 A spherical shell satellite (3-m-OD, 1.25-cm-thick stainless steel walls) re-enters the atmosphere from outer space. If its original temperature is 38°C, the effective average temperature of the atmosphere is 1093°C, and the effective heat transfer coefficient is , estimate the temperature of the shell after reentry, assuming the time of reentry is 10 min and the interior of the shell is evacuated.
A transformer is to be cooled via forced air convection. To increase the effectiveness of thecooling, Alloy 1095 cast aluminum fins are attached to the top of the transformer overwhich air is blown (negligible thermal contact resistance between the transformer and thefins). The fins are 2 cm thick and 7 cm long and span the entire length of the transformer,and the transformer is 7 cm wide and 10 cm long. Air leaves the cooling fan at 25°C .a) Decide how to model the fins before performing any real analysis. Youare willing to accept some error in your analysis and so you will either model thefins as having adiabatic tips or being infinitely long. You expect the average convectioncoefficient over the heat transfer surfaces for this system to be around 50 W m2– K⁄ .Which tip condition should you use for the fins in your analysis? b) Modeling the transformer as being isothermal, determine the average convectioncoefficient over the heat transfer surfaces.

A long stainless-steel (AISI 316) steam pipe, with an inside diameter of 6.00 cm and an outside diameter of 8.00 cm, is covered with a layer of asbestos insulation (k = 0.150 W/m-K) 1.00 cm thick, which in turn is covered with foam insulation (k = 0.044 W/m-K) 6.00 cm thick. The inside surface temperature of the stainless-steel steam pipe is measured to be 250.0°C, while the outside surface of the foam is exposed to convection, T_inf = 25.0°C, h_inf = 15.0 W/m^2-K. • Draw and label a sketch of this system.

A transformer that is L=20cm long, 6.2 cm wide, and 5 cm high is to becooled by attaching a 10 cm × 6.2 cm wide polished aluminum heatsink (emissivity =0.03) to its top surface. The heat sink has seven fins,which are 5 mm high, 2 mm thick, and 10 cm long. A fan blows air at25°C parallel to the passages between the fins. The heat sink is todissipate 20 W of heat and the base temperature of the heat sink is notto exceed 60°C. Assuming the fins and the base plate to be nearlyisothermal and the radiation heat transfer to be negligible, determinethe minimum free-stream velocity the fan needs to supply to avoidoverheating.

Water flows in a pipe of 0.0475 m inside diameter at a velocity of 1.5 m/s. Calculate the heat transfer coefficient if the temperature of the water is 60OC and 40OC at the inlet and the outlet of the pipe respectively, and the inside wall temperature of the pipe is 35OC. The physical properties must be calculated at the average water temperature. The thermal conductivity of the pipe at average temperature is 0.639 W/mOC.
