- A centrifugal pump loses prime after starting. The reason of this trouble may be
- For a specific centrifugal air blower operating at constant speed & capacity, the power requirement and pressure vary
- The range of a particular rotameter can be increased by
- Two liquids manometer is used for measuring small pressure differences in
- Pick out the wrong statement about a streamline.
- When larger particles e.g., grains are subjected to fluidisation, the corresponding bed produced is termed as the __________ bed.
- Co-efficient of velocity is __________ the coefficient of discharge.
- 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
- Which of the following has the minimum compressibility?

A.
It is always parallel to the main direction of the fluid flow |
|
B.
It is a line across which there is no flow and it is equivalent to a rigid boundary |
|
C.
Streamlines intersect at isolated point of zero velocity and infintie velocity |
|
D.
The fluid lying between any two streamlines can be considered to be in isolation and the streamline spacing varies inversely as the velocity |
