A shell and tube heat exchanger has a single shell and 4 tube passes. The shell diameter is 25-in. The shell contains 10 baffles with a spacing of 0.36 m. Liquid ammonia flows through the shell with a flow rate of 70 kg/s and an average temperature of 90°C. The tubes are 1¼-in 13 BWG tubes on a 1 9/16-in square pitch.
Determine the

a. Shell-side convective heat transfer coefficient (W/m2-K)
