- TL;DR Summary
- Would the pressure go up or down?
Imagine a firetruck with a hoseline attached to the pump. The pump is set to 800kpa with 100kpa loss due to friction in the 30m hoseline so you have 700kpa at the nozzle.
What would the pump's gauge read if you disconnected the hoseline?
I thought since there is no more resistance, the pressure gauge would show a much lower reading, maybe 0 because the pump's outlet is now at atmospheric pressure.
However, ChatGPT was telling me the gauge jumps to the static (deadhead) pressure of the pump.
