186) Normal depth in open channel flow is the depth of flow corresponding to

Answer is:

uniform flow

187) Uniform flow occurs when

the direction and magnitude of the velocity at all points are identical

the velocity of successive fluid paiticles, at any point, is the same at successive periods of time

the magnitude and direction of the velocity do not change from point to point in the fluid

the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each pleasure

Answer is:

the magnitude and direction of the velocity do not change from point to point in the fluid

188) Pitot tube is used for measurement of

Answer is:

velocity

Explanation:

Pitot Tube is a small open tube bent at right angle. Pitot tube is used to measure the velocity of flow at the required point in a pipe. It is determined by measuring the rise of liquid in a tube.

189) Hydrometer is used to determine

Answer is:

specific gravity of liquids
