Problem $03\mathrm{.}090-$ Superheated water vapor

The superheated water vapor is at $3\mathrm{.}5$ MPa and

$450C.$ 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.

Problem $03\mathrm{.}090.$c $-$ Ideal and compressible gas error

Determine the specific volume of superheated water based on data

from tables. Also, determine the error involved in the first two cases.

The specific volume is

$*\frac{m^3}{k}g.($Round the final answer to

three decimal places.$)$

The percentage error from ideal$-$gas equation is

The percentage error from compressibility chart is

$($Round the final answer to one decimal place.$)$
