Chapter 3, Problem 3.60P

Interpretation Introduction

(a)

Interpretation:

A formula for $h$ in terms of $L$ and $\theta$ is to be derived.

Concept introduction:

Manometer is a device used to measure pressure of gas or vapor at low levels. It is helpful in differentiating static and dynamic pressures. Its shape may be U-tube, inverted or a single tube.

Interpretation Introduction

(b)

Interpretation:

The pressure difference between point $1$ and $2$ is to be stated.

Concept introduction:

Manometer is a device used to measure pressure of gas or vapor at low levels. It is helpful in differentiating static and dynamic pressures. Its shape may be U-tube, inverted or a single tube.

Interpretation Introduction

(c)

Interpretation:

The formula derived in Part (a) is given to be not worked if the process fluid is a liquid instead of a gas. The one definite and another possible reason for it are to be stated.
