Questions and Answers

What is the formula to determine the pressure drop on the intake gauge?

Static pressure minus residual pressure (correct)
Static pressure plus residual pressure
Static pressure times residual pressure
Residual pressure divided by static pressure

If the static pressure is 70 psi and the residual pressure is 63 psi, what is the pressure drop percentage?

7.5%
15%
10% (correct)
9.5%

What additional gallons per minute can be added if the pressure drop is 12%?

Two times the current gpm (correct)
One times the current gpm
Three times the current gpm
No additional gpm can be added

Why is it important to base calculations on gallons per minute rather than the number of hoses?

Master Intake Gauge

A device measuring pressure in a water supply system to assess available flow.

Pressure Drop Calculation

The method to find out how much water is available based on pressure readings.

Static Pressure

The pressure in the system when no water is flowing, serving as a reference point.

Residual Pressure

The remaining pressure in the system after some flow is used; helps determine flow capacity.
