In the net discharge pressure chart, 150 psi corresponds to what percentage of discharge?

In the net discharge pressure chart, 150 psi corresponds to what percentage of discharge?

• A. 100%
• B. 70%
• C. 50%
• D. 25%

Answer: (A)

The net discharge pressure chart translates the pressure at the discharge into a percentage of the maximum designed discharge. The scale is set so that the highest net discharge pressure on the chart, 150 psi, corresponds to full, or 100%, discharge. So reading 150 psi on the chart means you’re delivering the maximum allowable discharge. In practice, if you see lower net discharge pressures on the chart, they map to lower percentages of discharge according to the scale, illustrating how much of the maximum flow you’re actually delivering.
