Chapter 18, Problem 25P

Use the portion of the given steam table for superheated ${\text{H}}_{\text{2}}\text{O}$ at 200 MPa to

(a) Find the corresponding entropy s for a specific volume v of 0.108 m³/kg with linear interpolation

(b) Find the same corresponding entropy using quadratic interpolation, and

(c) Find the volume corresponding to an entropy of 6.6 using inverse interpolation

$v\left({\text{m}}^{\text{3}}\text{/}\text{kg}\right)$	0.10377	0.11144	0.1254
$s\left(\text{kJ/kg}\cdot \text{K}\right)$	6.4147	6.5453	6.7664
