The condenser of a steam power plant operates at a pressure of 4.25 kPa. The condenser consists of 100 horizontal tubes arranged in a 10 × 10 square array. The tubes are 8 m long and have an outer diameter of 3 cm. If the tube surfaces are at 20°C, determine

(a) The rate of heat transfer from the steam to the cooling water

(b) The rate of condensation of steam in the condenser.
