Air that flows through the shell side of a 65-tubes (2 digits, read the instructions below), one-pass shell- and-tube heat exchanger is to be heat by water flowing at a rate of 15 kg/s. The length of the copper tubes is 8 m, and they have an outside diameter of 2.5 cm and an inside diameter of 2.3 cm. The convective heat transfer coefficients of the water and air are 1065 W/m2.K (4 digits, example 1071 W/m2 .K) and 200 W/m2 K, respectively. The air enters the shell at a temperature of 15°C and a flow rate of 16 kg/s. The temperature of the water as it enters the tubes is 75°C. a a) draw a schematic of the heat exchanger and calculate (b) the heat exchanger effectiveness, (c) the heat transfer rate to the air, and (d) the outlet temperature of the air and water. Write down all your assumptions.
