1. A. Using the Steam Tables, determine the amount of cooling water needed by a condenser in kg/sec if wet steam comes into the
condenser at P= 610.44mmHG vac and 99.47 % moisture, mass flow rate= 7200+ (X/SN) kg/hr. Cooling water enters the condenser at 12
deg C and leaves at 21 deg C. Answer:
B. Draw the schematic diagram of the condenser and process in the PV and TS
diagrams below. Cp H20 = 4.187 KJ/(kg-K):
