Saturated steam at 1.46 bar and 110°C condenses on a 25 mm outer diameter vertical tube which is 50 cm long. The tube wall is maintained at 100°C. Calculate the average heat transfer coefficient and the rate of condensation. Check that the condensate flow is laminar. The properties of the condensate at 150°Care k = 0.68 W/m K, r = 954.7 kg/m3,
