Answer:

5318.346

Explanation:

From the question we have

M = 6kg/s

P = 15kpa

h1 = 3248.4kj

x = 0.9

H2 is unknown

From the steam table

hf = 225.85

hg = 2599.36

H2 = HF + x(hg -hf)

h2= 225.85+0.9(2599.36 - 225.85)

= 225.85 + 0.9(2373.51)

= 225.85 + 2136.159

= 2362.009

To find The power generated by this turbine:

We insert all the parameters into the equation below:

m(h1 - h2)

= 6(3248.4 - 2362.009)

= 6 x 886.391

= 5318.346KW
