A steam generator consists of a bank of stainless stell (k=15 W/m·K) tubes habing the core configuration of CF7.0-5 and an inner diameter of 13.8 mm. The tubes are installed in a plenum whose square cross section is 0.6 m on a side, thereby providing a frontal area of 0.36 m2. Combustion gases whose propertires may be aproximated as those of atmospheric air, enter the plenum at 900 k and pass in cross flow over the tubes at 3 kg/s. There are 11 rows of tubes in the gas flow direction. If saturated water at 2.455 bar experiences boiling in the tubes, what is the gas exit temperature? A convection coeficient of 10.000 W/m2·K is associated with boiling in the tubes.

Q.8. Super-heated steam at 875 K is flowing through a thick walled tube of stainless tube with inside diameter 40mm and outside diameter50mm such that its inner wall is heated to a uniform temperature of 875K.To reduce heat loss, the tube is lagged with 30mm layer of asbestos insulation k=0.2 W/m.K. Calculate the heat loss using the electrical analogy per metre length if the outer surface temperature of the insulated tube is 350K.Thermal conductivity of steel=19 W/m.k.

A thick steel slab (ρ= 7800 kg/m3, c= 480 J/kg·K, k= 50 W/m·K) is initially at 300°C and is cooled by water jets impinging on one of its surfaces. The temperature of the water is 25°C, and the jets maintain an extremely large, approximately uniform convection coefficient at the surface. Assuming that the surface is maintained at the temperature of the water throughout the cooling, how long will it take for the temperature to reach 50°C at a distance of...
