Consider the Design Problem 10.2 (stated in Chapter 10), and the cooling water and steam inlet conditions specified. Design this steam condenser by calculating both the condensing heat transfer coefficient and the cooling water heat transfer coefficient.

Data from in Design Problem 10.2

Saturated steam vapor leaves a steam turbine at a mass flow rate of 2 kg/s and a pressure of 0.5 atm, as shown in the following diagram. Design a heat exchanger to condense the vapor to the saturated liquid state using water at 10°C as the coolant. Use a condensing heat 

transfer coefficient in the middle range given in Table 1.5. In Chapter 9, methods for calculating the condensing heat transfer coefficient are given.
