Chapter 3, Problem 3.52P

Interpretation Introduction

(a)

Interpretation:

The gauge pressure $\left(\text{kPa}\right)$ at the tap and the junction is to be calculated.

Concept introduction:

The gauge pressure $\left(P_{\text{g}}\right)$ is the difference between the actual pressure $\left(P\right)$ and atmospheric pressure $\left(P_{\text{a}}\right)$. It is calculated by the formula,

$P-P_{\text{a}}=\text{ρ}gh=P_{\text{g}}$

Interpretation Introduction

(b)

Interpretation:

A possible explanation for the lower value of pressure at the tap estimated in Part (a), but the measurement at junction is as predicted, is to be stated.

Concept introduction:

Water is an incompressible fluid. The fluid pressure is directly proportional to the cross-sectional area and inversely proportional to the velocity.

Interpretation Introduction

(c)

Interpretation:

The responsible factors for the low water flow to the sink are to be stated.

Concept introduction:

Water is an incompressible fluid. The fluid pressure is directly proportional to the cross-sectional area and inversely proportional to the velocity.
