Question

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 1

The answer is "83.98, 1889.195, and 1889.195"

Step-by-step explanation:

Given value:

`\bold{P_(4)=2.34 \ kPa}`

In point a:

The value of
`h_(f4)=83.915 \ \ (Kj)/(kg)\\`

`V_4=0.001002 \ \ (Kj)/(kg)\\\\U_4= 83.98 \ \ (Kj)/(kg)\\\\`

In point b:

calculating heat leaves formula=
`h_3-h_(f4)`

`= 1973.11-83.915\\\\= 1889.195 \ \ (KJ)/(kg)`

In point c:

calculating Heat transfer rate formula
`=m(h_3-h_4)`

`= 1(1889.195)\\\\ = 1889.19 \ \ kw.`
