Required information

The superheated water vapor is at $15$MPa and $350C.$ The gas constant, the critical pressure, and the critical temperature of water are $R=0\mathrm{.}4615$kPa$*\frac{m^3}{k}g*K,T_{cr}=647\mathrm{.}1K,$ and $P_{cr}=22\mathrm{.}06$MPa. Use data from the steam tables.

NOTE: This is a multi$-$part question. Once an answer is submitted, you will be unable to return to this part.

Determine the specific volume of superheated water vapor based on data from tables. Also, determine the error involved in the first two cases.

The specific volume is $,\frac{m^3}{k}g.$

The percentage error from ideal$-$gas equation is

$\%.$

The percentage error from compressibility chart is

$\%$THE ANSWER IS NOT $8\mathrm{.}5$ OR $0\mathrm{.}51$
