Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The Total Energy Line (TEL) in open channel or pipe flow is sum of pressure head, elevation head and velocity head of flowing fluid in respect to a reference line. Reason R: The Hydraulic Grade Line (HGL) under same conditions is obtained by subtracting velocity head from total energy line. In the light of the above statements, choose the most appropriate answer from the options given below

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: In pumps, suction lift exists when the source of water supply is below the centre line of pump. Reason R: Total static suction lift is the sum of static suction lift minus friction losses, entrance losses in the suction piping.

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: In a centrifugal pump, the function of impeller is to impart high velocity of water so that velocity head is increased. Reason R: The function of casing is to reduce velocity of water so that velocity head is reduced and converted into pressure head. In the light of the above statements, choose the most appropriate answer from the options given below

A centrifugal pump at its best point of efficiency discharges \(0.04 \, \text{m}^3/\text{sec}\) against a total head of \(42 \, \text{m}\). When the speed of pump is \(1370 \, \text{rpm}\), compute the specific speed of the pump.
