Steam is used on the shell-side of a vertical shell/tube exchanger to heat water. Given the following: Do=0.75,in There are 100 tubes 10ft long Condensing temperature =300F and Heat of Vaporization =1050btu/lb The tube wall temperature can be assumed to be 220F What is the condensate film temperature, F ? 6 Hint: The correct condensate film temperature is 240F Also given: cond viscosity at 240=0.61468lb/fth cond k at 240=0.394 btu /fthF cond cp at 240=1.0btu/lbF cond density at 240=58.2lb/ft3 What is the condensate prandtl number, Pr? b Assumming that condensate is produced at the rate of 7905lbs/hr : What is the condensate loading, lbs/hr-ft? Hint: The correct condensate loading =402.6,lbs/hrft What is the condensate Nre? 6 What is the Nusselt number? s What is ho, btu/lb-ft2-F
