Chapter 13, Problem 13.30P

Interpretation Introduction

Interpretation:

The rate $\left(\text{kg/h}\right)$ at which the liquid water is removed from the steady state flow process of the moist air is to be calculated.

Concept Introduction:

The mole fraction of a species $\left(y_i\right)$ in a mixture is given by:

  $y_i=\frac{p_i}{P}$   ....... (1)

Here, $p_i$ is the partial pressure of the species in the mixture and $P$ is the total pressure of the mixture.

Antoine equation is used to determine the vapor pressure of any substance at the given temperature by the equation:

  $\ln P^{\text{sat}}\left(\text{kPa}\right)=A-\frac{B}{\left(T^{\circ }\text{C}\right)+C}$   ...... (2)

Here, $A,B\text{ and }C$ are the constants specific for a substance given in table B.2 of appendix B.

According to the law of conservation of mass, mass can neither be created nor be destroyed.
