Chapter 6, Problem 6.69P

Interpretation Introduction

Interpretation:

Determine the heat that must be added during process in which some quantity of water is pumped into a tank have liquid water in equilibrium with its vapor.

Concept Introduction:

Since given problem is associated with both mass and energy changes, so we consider general energy balance here which is defined as:

  $\frac{d{\left(mU\right)}_{\text{tank}}}{dt}+\Delta \left[\left(H+\frac{1}{2}{U}^2+zg\right)\stackrel{•}{m}\right]=\stackrel{•}{Q}+\stackrel{•}{W}$.....(1)
