**CE6303 MECHANICS OF FLUIDS QUESTION BANK **

**UNIT-I 2-marks**

1. Define “Pascal’s Law”:

It stats that the pressure or intensity of pressure at a point in a static fluid is equal in all directions.

2. What is mean by Absolute pressure and Gauge pressure?

Absolute Pressure:

It is defined as the pressure which is measured with the reference to absolute vacuum pressure.

Gauge Pressure:

It is defined as the pressure which is measured with the help of a pressure measuring instrument, in which the atmospheric pressure is taken as datum. The atmospheric pressure on the scale is marked as zero.

3. Define Manometers.

Manometers are defined as the devices used for measuring the pressure at a point in a fluid by balancing measuring the column of fluid by the same or another column of fluid.

- Simple M
- Differential M

5. Define Buoyancy.

When a body is immersed in a fluid, an upward force is exerted by the fluid on the body. This upward force is equal to the weight of the fluid displaced by the body and is called the force of buoyancy or simply buoyancy.

6. Define META – CENTRE

It is defined as the point about which a body starts oscillating when the body is fitted by a small angle. The meta – centre may also be defined as the poit at which the line of action of the force of buoyancy wil meet the normal axis of the body when the body is given a small angular displacement.

7. Write a short notes on “ Differential Manometers”.

Differential manometers are the devices used for measuring the difference of

pressures between two points in a pipe or in two different pipes/ a differential manometer consists of a U – tube containing a heavy liquid, whose two ends are connected to the points, whose difference of pressure is to be measured. Most commonly types of differential manometers are:

- U – tube differential manometer.
- Inverted U – tube differential manometers.
