Steam flowing at a rate of 10,000 kg/h and at 120°C is condensed using cooling water at an average temperature of 20°C. The condenser contains 800 tubes which have an outer diameter of 18 mm. Estimate the heat transfer coefficient (a) if the condenser is vertical and (b) if the condenser is horizontal with tubes 3 m long and condensation takes place outside the tubes.
