The core of a shell-and-tube heat exchanger contains 60 tubes (single-tube pass) with an inside diameter of 2.5 cm and length of 2 m. The shell inside diameter is 35 cm. The air, which flowsthrough the tubes at a flow rate of 1.5 kg/s, is to be heated from 100°c to 300°c.
a. Calculate the total pressure drop as the sum of the frictional pressure drop in the tube and the pressure drop due to acceleration, abrupt contraction (kc = 0.25), and abrupt enlargement (ke = 0.27). Is the total pressure drop smaller than the frictional pressure drop in the tube? Why?
b. Calculate the fan power needed.
