Determine the specific volume of superheated water vapor at 15 mpa and 1000c, using (a) the ideal-gas equation, and (b) the steam tables.

a)

b)

Explanation:

Given that

Pressure P = 15 MPa

Temperature = 1000 C = 1273 K

a)If assume as ideal gas

The gas constant for super heated steam R is 0.461 KJ/kg.K.

We know that ideal gas equation

P v  =RT

15 x 1000 x v =0.461 x 1273

b) By using steam table

From steam table we can see that volume of super heated vapot at 15 MPa and 1273 K .
