A positive displacement pump (PDP) is operating in an open system ___

A positive displacement pump (PDP) is operating in an open system.

PDP parameters are as follows:

PDP speed = 1,000 rpm
PDP discharge pressure = 2,000 psig
PDP suction pressure = 50 psig
PDP flow rate = 150 gpm

Which one of the following changes will cause PDP flow rate to exceed 200 gpm?

A. A second identical discharge path is opened.
B. PDP speed is increased to 1,500 rpm.
C. PDP suction pressure is increased to 120 psig.
D. Downstream system pressure is decreased to 1,000 psig.
