Fluid Mechanics MCQ with Answers

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

Answer is:

uniform flow

187) Uniform flow occurs when

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

190) The total energy of each particle at various places in the case of perfect incompres sible fluid flowing in continuous sream
