Water at the rate of 5 kg/s is heated from 37.78 to 54.44 ˚C in shell and tube heat exchanger. On the shell side one pass is used with water as the heating fluid, 2 kg/s, entering the exchanger 93.33 ˚F. The overall heat exchanger coefficient is 1500 W/m2 .˚C, and the average water velocity in the ¾-in diameter tubes (1.905 cm). Because of space limitations, the tube length must not be longer than 2.438. Calculate the number of tube passes, the number of tubes per Passes, and the length of the tubes, consistent with this restriction.
