A single-effect evaporator (SEE) is to generate a distillate product at a flow rate of 1 kg/s. The system operating temperatures are as follows: The boiling temperature, Tb, is 75 °C. The intake seawater temperature, Tcw, is 25 °C. The feed temperature, Tf, is 70 °C. The steam temperature, Ts, is 82 °C. Determine: a) The heat transfer areas in the evaporator and the condenser, b) The thermal performance ratio, c) The flow rates of feed seawater and reject brine, and d) The flow rate of cooling seawater
