Fluid Mechanics - Section 1 (6)

The net positive suction head (NPSH) of a centrifugal pump is defined as the sum of the velocity head and the pressure head at the

Schedule number of a pipe, which is a measure of its wall thickness, is given by

Most commonly used joint in the underground pipe lines is the

The head loss in turbulent flow in a pipe varies

Hydraulic mean depth (Dm) for a circular pipe of diameter 'D' flowing full is 0.25 D. For a circular channel, at Dm = 0.3 D, gives the condition for the maximum

Head developed by a centrifugal pump depends on its

The normal stress is the same in all directions at a point in a fluid, when the fluid is

When the momentum of one fluid is used for moving another fluid, such a device is called a/an
