A condenser is used to condense saturated steam to saturated liquid at 150°C (shell) using a process stream entering at 30°C and exiting at 50°C (tubes). Assume that the condensation resistance is negligible compared to that of the process stream. The condensation throughput must be decreased by 50%. By what factor must the flowrate of the process stream be reduced?

The T-Q diagram for this problem is shown in Figure E20.20.
