Pressure p1 is equal to 10 kpa which is equal to 10 into 10 to the power 3 pa.
00:10
P2 is equal to 7 mpa which is equal to 7000 into 10 to the power 3 pa.
00:19
At pressure p1, the specific heat enthalpy h1 is equal to hf1 is equal to 191 .81 kj per kg.
00:36
Hf2 is equal to 2392 .1 kj per kg.
00:47
V1 is equal to 0 .00101 cu.
00:54
M per kg.
00:55
The work done is equal to p delta v.
01:02
Delta v is the change in volume.
01:14
For the isochoric process, work done per unit mass is equal to v1 into p2 minus p1.
01:26
Substitute the values in this equation.
02:11
H2 is equal to 198 .87 kj per kg.
02:19
At pressure p2, that is equal to 7 mpa and temperature of 500oc, h3 is equal to 3411 .4 kj per kg.
02:40
The packing fraction x is equal to 0 .8201.
02:47
H4 is equal to hf1 plus s hfg.
02:55
Substitute the values in this equation.
02:58
191 .81 plus 0 .8201 into 2392 .1 is equal to 2153 .6 kj per kg...
