Hello in this question we have to determine the mass flow rate of steam through the turbine here.
00:05
So as in this question, p1 is given as here 7 mpa, t1 is given as here 5 ,500 degree centigrade, v1 is given as here 45 meter per second here.
00:19
And now come to p2.
00:20
P2 is equal to 100 kps here.
00:23
V2 is equal to 75 meter per second here.
00:26
So the power impact omega -0 is equals to 5 of m.
00:31
W here which is power impact here and isotropic efficiency ita is equals to 77 % here from the steam table it is seen that the state for stream is in the in the reason hence from steam table at p1 is b1 and t1 h1 is equals to here 3 ,411 .3 kilojoule per kg here and s1 is equals to here 6 .7997 kilojoule per k g kelvin here now we'll determine the final entropy from the is centropic process hence s2 is equals to s1 s2 is equals to s1 is 6 .7997 kilojoule per kg kelvin here we have to determine the quality of mixture after the is centropic process here so s2 is equals to as here s2 is equals to as here s2 is equals to as f2 into sfg2 here.
01:31
So by substituting value, sf2 is equal to 1 .3028 kilojoule per kg kelvin here at p equals to 100 kpa.
01:42
And sfg2 is equal to 6 .0562 kilojoule per kg kelvin here...
