32. A process stream is condensed and the heat released is used to produce steam in a counter-current heat exchanger. The process stream condenses at 465F. Feedwater enters the heat exchanger at 120F with saturated steam being produced at 440F. h = 89 Btu/lb at 120F h = 419 Btu/lb at 440F Hy = 1205 Btu/lb at 440F The percentage of the hear transferred to the water that is used to heat the liquid(sensible heat) is a. 20% b. 30% C. 40% d. 50%
