Chapter 6, Problem 6.33P

(a)

Interpretation Introduction

Interpretation:

The volumetric discharge rate from the nozzle is to be calculated.

Concept Introduction :

The pressure and velocity at two different locations is calculated by applying the Bernoulli’s equation.

The Bernoulli’s equation between two points is,

  $\frac{P_1}{\rho }+\frac{v_1^2}{2}+g{z}_1=\frac{P_2}{\rho }+\frac{v_2^2}{2}+g{z}_2$

The formula for calculating the volumetric flow rate is,

  $\dot{V}=A\times v$

(b)

Interpretation Introduction

Interpretation:

The pressure and the velocity at point $\text{A,B,C}\text{and}\text{D}$ is to be calculated.

Concept Introduction :

The pressure and the velpocity at two points is calculated by the bernoulis equation.

The Bernoulli’s equation between two points is,

  $\frac{P_1}{\rho }+\frac{v_1^2}{2}+g{z}_1=\frac{P_2}{\rho }+\frac{v_2^2}{2}+g{z}_2$

The pressure at the same level between two points remains equal.
