Question
Steam in the condenser of a thermal power plant is to be condensed at a temperature of with cooling water which enters the tubes of the condenser at and exits at . The total surface area of the tubes is , and the overall heat transfer coefficient is . The heat transfer (in MW) to the condenser is ______ (correct to two decimal places).
Correct answer
1.14 to 1.16
Solution
1.Identify the temperatures:
- Hot fluid (steam) temperature: (isothermal condensation)
- Cold fluid (water) temperatures: ,
4.Calculate the heat transfer rate ():
Rounding to two decimal places, we get 1.15 MW.Continue learning with Success Tracker
