Fluid Mechanics MCQs

In case of hydraulically smooth pipe, the resistance to flow depends only on the Reynolds number, whereas for a hydraulically rough pipe, the resistance to flow is governed by the relative roughness. Two pipes are said to have the same hydraulic roughness, when they have equal values of

The most economical flow control valve for use with large diameter pipes is a

Two dimensional stream function

__________ is an example of axial flow impeller.

Water is flowing at 1 m/sec through a pipe (of 10 cm I.D.) with a right-angle bend. The force in Newtons exerted on the bend by water is
