A condenser accepts steam from the turbine in problem 2 at a pressure of 2.34 kPa. Saturated water at the same pressure leaves the condenser. (Note: 20 C is the saturation Temperature for 2.34 kPa)) a. Give P, v, u, h and s for the saturated liquid water leaving the condenser. b. How much heat leaves the condenser per kg of steam? c. What is the heat transfer rater from the condenser, assuming a water flow of 1 kg/s,

Answer:

The answer is "83.98, 1889.195, and 1889.195"

Explanation:

Given value:

[tex]\bold{P_{4}=2.34 \ kPa}[/tex]

In point a:

The value of [tex]h_{f4}=83.915 \ \ \frac{Kj}{kg}\\[/tex]

[tex]V_4=0.001002 \ \ \frac{Kj}{kg}\\\\U_4= 83.98 \ \ \frac{Kj}{kg}\\\\[/tex]

In point b:

calculating heat leaves formula= [tex]h_3-h_{f4}[/tex]

                                                      [tex]= 1973.11-83.915\\\\= 1889.195 \ \ \frac{KJ}{kg}[/tex]

In point c:

calculating Heat transfer rate formula[tex]=m(h_3-h_4)[/tex]

                                                              [tex]= 1(1889.195)\\\\ = 1889.19 \ \ kw.[/tex]
