- QUESTION 3 A multi-stage steam turbine exhausts into a two-pass surface condenser operating at a pressure of 10kPa. The steam enters the condenser with a dryness fraction of 0.85 and the condensate leaves the condenser at a temperature of 34.6°C. The tubes have an inside diameter of 18mm and a wall thickness of 1mm. Coolina water circulates through the tubes at a speed of 1.2m/s. The stean flows through the condenser at a rate of 2400kg/hr and air leaks into the system at a rate of 0.5kg/1000kg of steam condensed.

Saturated steam at 0.135 bar condenses on the outer surface of the tube, while water at a mean temperature of 295 K is in fully developed flow through the tube (you can assume that 295 K is the mean temperature in the axial direction of the tube (e.g. along its length) or you may assume that the inlet water temperature is 295 K).
