Question 1
Manometric head developed 
in m, and discharge Q in lps in respect of two pumps, 1 and 2, are tabulated. The pumps are connected in series against a static head of 100 m. Total head losses for a discharge of Q are as 
What is the delivered discharge?

A reciprocating pump has a stroke of 30 cm, speed of 100 rpm, and a piston of 
diameter. It discharge is 
What is the slip of the pump?
diameter. It discharge is What is the slip of the pump? Question 3
The following data were recorded when a centrifugal pump worked at its maximum efficiency: Q = 40 lps ; Manometric head developed = 25 m; Input shaft horse power = 11.9 W. What is the non-dimensional specific speed of the pump it it was running at 1500 rpm? (May adopt the following (all in S.I. units):
Question 4
Assertion (A): The efficiency of a reciprocating pump is 10-20 percent higher than that of a centrifugal pump for comparable discharge-head conditions.
Reason (R): The discharge from a reciprocating pump is dependent upon speed.
Reason (R): The discharge from a reciprocating pump is dependent upon speed.
Question 5
Consider the following statements:
The total head against which a pump has to work must include, besides any other items,
1) the suction lift.
2) the delivery head
3) the head lost due to friction at entrance in the rising main
4) the head lost due to friction at exit in the rising main.
Which of these statements are correct?
