Question: Steam flows through a condenser at 2 10 6 kg/hr, entering as saturated vapor at 40C, and leaving at the same pressure as subcooled

Steam flows through a condenser at 2 × 10⁶ kg/hr, entering as saturated vapor at 40°C, and leaving at the same pressure as subcooled liquid at 30°C. Cooling water enters the condenser pipes at 18°C and 1.5 bar. Assume no pressure loss occurs in the pipes. Environmental regulations require that the exit temperature is at maximum 20°C. Determine the minimum cooling water flow rate.
