Chapter 10, Problem 128AE

Interpretation Introduction

Interpretation:

The amount of pressure that would have to be applied to steam at ${\text{350}}^{\text{0}}\text{C}$ to condense the steam to liquid should be determined.

Concept introduction:

Clausius- Clapeyron Equation is used to estimate the vapor pressure at another temperature, if the vapor pressure is known at some temperature, and if the enthalpy of vaporization is known.

$\frac{\text{1}}{\text{p}}\frac{\text{dp}}{\text{dT}}\text{=}\frac{\text{ΔH}}{{\text{RT}}^{\text{2}}}$

Where, $\text{ΔH}$ the change in enthalpy, R is is the universal gas constant, $\text{T}$ is the temperature in absolute scale and $\text{p}$ is the pressure.

To determine: The amount of pressure that would have to be applied to steam at ${\text{350}}^{\text{0}}\text{C}$ to condense the steam to liquid
