A centrifugal pump convert mechanical energy to pressure ene

A centrifugal pump convert, mechanical energy to pressure energy (head) It work.... by pure phenomenal magic as the impeller sucks, the fluid into the pump and then rapidly expels it in the discharge pipe. because the impeller imparts a velocity to the fluid, and the casing subsequently collects and converts the velocity to pressure head. because the impeller sucks the fluid from the suction side of the system and creates a pressure by utilizing Charles\'s and Bernoulli\'s Law of Ideal Oases and Fluids in a pressure temperature relationship (fixed volume and constant temperature) If you double the operating speed of a centrifugal pump... the flow rate will double (simple speed ratio). the head generated will increase by a factor of 4 (speed ratio squared) all of the above: a. and b flow, bead will all simply double.

Solution

[1] Answer is option (c)

[2] Flow rate is directly proportional to speed

So flow rate doubles

Head is proportional to square of speed

So head increases by factor 4

Answer is option (d) all of the above a and b
