1) The superheated water vapor is at 15 MPa and 350°C. The gas

constant, the critical pressure, and the critical temperature of water

are R = 0.4615 kPa m³/kg-K, Tcr= 647.1 K, and Pcr= 22.06 MPa. Use

data from the steam tables.

a) Determine the specific volume of superheated water based on the

ideal-gas equation.

b) Determine the specific volume of superheated water based on the

generalized compressibility chart.

c) Determine the specific volume of superheated water based on

data from tables.

d) Determine the error involved in the first two cases (a and b).
