5.44 A 20% magnesium chloride solution is flowing at a rate of 240,000 lbm/h through the shell side of a STHX. The average temperature of the magnesium chloride is 25°F. The shell has a diameter of 17¼ in. and there is 1-tube pass.

The shell contains 12 baffles with a spacing of 10 in. The tubes are ¾ in. 15 BWG tubes on a 1-in. triangular pitch. Determine the following:

a. Shell-side convective heat transfer coefficient (Btu/h·ft2·°F)

b. Shell-side pressure drop (psi)
