A liquid stream contains 1 lb_m/s of the compound at T = 100°F and P = 1 atm. It needs to be boiled and heated to P = 1 atm and 175°F, as that is the temperature at which it must enter a chemical reactor. This heating/boiling process is to be carried out in a shelland-
tube heat exchanger with steam at P = 1 bar and T = 300°C to be used as the source of the heat. Find the flow rate of entering steam required if

A. The steam exits the heat exchanger as saturated vapor at P = 1 bar.

B. The steam condenses completely, and exits the heat exchanger at saturated liquid at P = 1 bar.
