During a flow test on a fire hose connection with a pressure regulating device in place, what should be determined and recorded on the inlet and outlet sides of the device?

• A. Pressure
• B. Flow rate
• C. Temperature
• D. Humidity

Answer: (A)

The test is checking how the pressure behaves across the pressure regulating device. You determine and record the pressures on both the inlet side and the outlet side of the regulator. This shows whether the regulator is receiving adequate supply pressure and, more importantly, whether it is delivering the correct downstream pressure under the tested flow. The difference between the two pressures reveals the regulator’s pressure drop and should align with the device’s specifications or the test procedure. Temperature and humidity aren’t the focus here, and while flow rate matters for overall performance, the essential measurement for this step is pressure on both sides.
