1.Draw an indicator diagram of a single-acting reciprocating pump considering

acceleration and friction. What would be the change in the indictor diagram if an

air vessel is attached (a) to suction side only, (b) to the delivery side only, and (c)

to both the suction and delivery sides.

2. Draw indicator diagram for the following cases of a reciprocating pump:

(a) When no air vessel is installed

(b) When air vessel is installed on suction side close to the pump

(c) When air vessel is installed on delivery side close to the pump

(d) When air vessels are installed on both sides of the pump and both are close to

the pump.
