# Reconsider Prob. 1077. Using EES (or other) software, investigate the effect of the condenser pressure on the rate of heat

## Question:

Reconsider Prob. 10–77. Using EES (or other) software, investigate the effect of the condenser pressure on the rate of heat transfer and the rate of condensation of the steam. Let the condenser pressure vary from 3 kPa to 15 kPa. Plot the rate of heat transfer and the rate of condensation of the steam as a function of the condenser pressure, and discuss the results.

**Data from problem 77**

The condenser of a steam power plant operates at a pressure of 4.25 kPa. The condenser consists of 100 horizontal tubes arranged in a 10 × 10 square array. The tubes are 8 m long and have an outer diameter of 3 cm. If the tube surfaces are at 20°C, determine

(a) The rate of heat transfer from the steam to the cooling water

(b) The rate of condensation of steam in the condenser.
