A surface condenser serving 50,000 kW steam turbo-generator unit receives exhaust steam at the rate of 196,000 kg/hr. Vacuum in condenser is 702 mmHg. Sea water for cooling enters at 29.5 deg C and leaves at 37.5 deg C. For steam turbine condenser, manufacturers consider 950 Btu/lb of steam turbine condensed as heat given up to cooling water. Calculate the logarithmic mean temperature difference.
