Chapter 7, Problem 7.60P

Interpretation Introduction

(a)

Interpretation:

The maximum elevation should be estimated.

Concept introduction:

The Bernoulli’s equation is given below

$\frac{\Delta P}{\rho }+\frac{\Delta U^2}{2}+g\Delta z+F=\frac{W_s}{m}$

Where, $W_s$ = work done on the fluid, $\rho$ =density, m = mass, F = frictional loss, u = velocity, $\Delta z$ = elevation of the point g = acceleration due to gravity

Interpretation Introduction

(b)

Interpretation:

1. The reason for the pressure at the inlet to be greater than that in part (a) should be explained.
2. The reason for the need of large pump should be explained.
