Hydraulics and fluid mechanics MCQ with Answers

186) Water is a __________ fluid.

Answer is:

newtonian

187) The celerity (velocity) of a pressure wave in a fluid is given by (where K = Bulk modulus, and ? = Density of the fluid)

Answer is:

K/?

188) The pressure intensity in kN/m² (or kPa) at any point in a liquid is (where w = Specific weight of liquid, and h = Depth of liquid from the surface)

Answer is:

wh

189) The hydraulic gradient line is always parallel to the centre line of the pipe.

Answer is:

Incorrect

190) Barometer is used to measure

Answer is:

atmospheric pressure

Explanation:

Atmospheric pressure: The atmospheric air exerts a normal pressure upon all surfaces with which it is in contact and it is known as atmospheric pressure. Atmospheric pressure is also known as barometric pressure. Barometer is used to measure atmospheric pressure.
