Steam condenses at 50C on the tube bank consisting of 20 tubes arranged in a rectangular array
Question:
Steam condenses at 50°C on the tube bank consisting of 20 tubes arranged in a rectangular array of 4 tubes high and 5 tubes wide. Each tube has a diameter of 6 cm and a length of 3 m, and the outer surfaces of the tubes are maintained at 30°C. The rate of condensation of steam is
(a) 0.054 kg/s
(b) 0.076 kg/s
(c) 0.315 kg/s
(d) 0.284 kg/s
(e) 0.446 kg/s
