In the event of a failure in the inert gas plant during discharge _____

the inert gas plant must be operational within one hour of failure and the discharge may continue for this time.

Which of these statements represents the advantage of rotary pumps as compared to reciprocating pumps?

The high discharge pressure of the rotary pumps permits a larger volume of fluid per unit time than the reciprocating pump.
Rotary pumps eliminate discharge slippage of the pumped liquid, while this does not hold true for a reciprocating pump.
Rotary pumps are capable of pumping more fluid than reciprocating pumps of the same weight.
Rotary pumps occupy only one-half the space of reciprocating pumps.
