Chapter 7, Problem 7.62P

Interpretation Introduction

(a)

Interpretation:

The pressure difference and height to the pipe inlet should be calculated.

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:

The change in the answer should be explained if the pipes were not smooth.

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

(c)

Interpretation:

The possible environmental impacts due to this operation should be discussed.

Concept introduction:

The Bernoulli’s equation is given below
