The one-pass condenser, heat exchanger shown in the sketch has 64 tubes arranged in a square array with 8 tubes per line. The tubes are 4 ft long and are made of copper with an outside diameter of 0.50 in. They are contained in a shell at atmospheric pressure. Water flows inside the tubes, whose outside wall temperature is 208.4°F. Calculate
(a) the rate of steam condensation and
(b) the temperature rise of the water if the flow rate per tube is 0.1 lb/s. Answer in SI and English units.
