Answer 1

To measure static pressure in a pipe, oneuses a pressure gauge connected to a suitable differential manometer for the determination of flow velocity and hence the flow rate.

Answer 2

Answer:

Piezometer tapping

Explanation:

Piezometer is the simplest form of manometer used for measuring gauge pressure.

One end of this manometer is connected to the point where the pressure is to be measured and the other end is open to the atmosphere.

As one end is open to atmosphere so it can’t be used for measuring the gas pressure.

Gas pressure cannot be measured by means of piezometers because a gas forms no free atmosphere surface and it can’t be used when large pressures in the lighter liquid are to be measured.

Therefore, For measurement of static pressure in a pipe, Piezometer is used.

Measurement:

1. Pitot tube → Velocity

2. venturimeter → Rate of flow

3. orificemeter → Rate of flow

4. A pressure gauge connected to a piezometer tapping.
