Chapter 7, Problem 7.27P

Interpretation Introduction

(a)

Interpretation:

Calculate the required heat input.

Concept introduction:

The open-system energy balance equation is,

$Q-W_S=\Delta H+\Delta E_K+\Delta E_P$

Where, $Q$ = heat absorbed by the system, $W_S$ = Shaft work done by the system on the surroundings, $\Delta H$, $\Delta E_K$ and $\Delta E_P$ are internal energy, kinetic energy and potential energy respectively.

Interpretation Introduction

(b)
