Hello candidate,

There are most commonly four types of hydraulic pumps which are used in daily uses and they are namely-

Gear pumps.

Piston pumps.

Rotary vane.

Screw pumps.

Hope you found it helpful. If you have any other queries regarding college admissions, entrance examination details, cut off list, or any other educational related doubts feel free to post it here.

Hello there,

Open-channel flows are those that are not entirely included within rigid boundaries; a part of the flow is in contract with nothing at all, just empty space.

Steady flow in a channel can be either Uniform or Non-uniform (varied).When the average velocities in successive cross sections of a channel are the same, the flow is uniform. This occurs only when the cross section is constant. Non-uniform flow results from gradual or sudden changes in the cross sectional area.

Characteristics of uniform flow in open channel are as follows:

• Open channel flow is characterized by a flow not completely enclosed by solid boundaries
• Free surface is subject to atmospheric pressure
• Flow is not caused by external head but by the gravity component along the slope of the channel

I hope it helps.

Hiii there,

Dear candidate, hope you are doing well, but this is not a correct way to ask your question and this is not a correct platform. Even if we can answer but your question is not answerable because it's not complete and I hope this solves your concern.

Thank you!!!
