PLEASE REFER TO ROGERS AND MAYHEW STEAM PROPERTY TABLES 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) b) the local film condensation heat-transfer coefficient at the bottom of the tube. [12 marks] the average condensation heat-transfer coefficient over the entire length of the tube. [9 marks] c) the total condensation rate at the tube surface. [4 marks]
