5.43 A STHX 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. Water flows through the shell with a flow rate of 70 kg/s and an average temperature of 85°C. The tubes are 1¼-in. 13 BWG tubes on a 1 9 16-in. square pitch. Determine the following:

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

b. Shell-side pressure drop (kPa)
