Question 3 This question requires the use of the steam property tables (Rogers and Mayhew) uploaded on QM+ exam section. All properties should be evaluated at the temperature of the steam. Saturated, pure steam at a temperature of 170 °C condenses on the outer surface of a vertical tube of outer diameter 2 cm and length 1.5 m. The tube surface is maintained at a uniform temperature of 150 °C. Calculate: a) the local film condensation heat-transfer coefficient at the bottom of the tube. b) the average condensation heat-transfer coefficient over the entire length of the tube. c) the total condensation rate at the tube surface.
