An operator is monitoring the performance of a cooling water pump.
The graph below shows the pump's performance curve, indicating the flow rate at various discharge pressures.
If the system requires a flow rate of exactly 150 gallons per minute (GPM), what is the corresponding discharge pressure in PSI?
**Pump Performance Curve**
(A line graph with 'Discharge Pressure (PSI)' on the Y-axis from 0 to 120 and 'Flow Rate (GPM)' on the X-axis from 0 to 250.
The curve starts high on the left and slopes down to the right.)
*Key Data Points on the Curve:*
- (50 GPM, 100 PSI)
- (100 GPM, 80 PSI)
- (150 GPM, 60 PSI)
- (200 GPM, 40 PSI)
