A steam pipe is covered with two layers of insulation. The inner layer (k = 0.17 W/m-K) is 30 mm thick and outer layer (k = 0.023 W/m-K) is 50 mm thick. The pipe is made of steel (k = 58 W/m-K) and has inner diameter and outer diameter of 160 and 170 mm, respectively. The temperature of saturated steam is 300 °C and the ambient air is at 50 °C. If the inside and outside heat transfer coefficients are 30 W/m²K and 5.8 W/m²-K respectively, calculate the rate of heat loss per unit length of the pipe.
An aluminium pipe carries steam at 110 °C. The pipe (k 185 W/m °C) has an inner diameter of 100 mm and an outer diameter of 120 mm. the pipe is located in a room where the ambient air temperature is 30 °C and the convective heat transfer coefficient between the pipe and air is 15 W/m2°C. .2.1) Neglecting the convective resistance of the steam, determine the heat transfer rate per unit length of pipe. hs o 1101 2.2) To reduce the heat loss from the pipe, it is covered with a 50 mm thick layer of insulation (k 0.20 W/m C). Determine the heat transfer rate per unit length from the insulated pipe. Assume negligible convective resistance from the steam

The topping cycle is a gas-turbine cycle that has a pressure ratio of 8. Air enters the compressor at 300 K and the turbine at 1300 K. The isentropic efficiency of the compressor is 80%, and that of the gas turbine is 85%. The bottoming cycle is a simple Rankine cycle operating between the pressure limits of 7 MPa and 5 kPa. Steam is heated in a heat exchanger by the exhaust gases to a temperature of 500°C and the isentropic efficiency of the turbine is 90 %. The exhaust gases leave the heat exchanger at 450 K.
