thanks everyone for the replies.
the information about the expansion of the pipework is really good.
So after carrying out further tests it does look that the expansion from 5-4 bar is present but also coupled with a leak.
The water pressure does continue to drop but at a much slower rate...
Thanks for the replies,.
The system is a geothermal heat pump circulation loop buried approximately 1m below the surface. Hence why it can't be observed
The pipework consists of 1200m of 32mm plastic pipe and 150m 65mm plastic pipe. The temperature over the test time is constant at approx 10...
Hi guys/gals
I am trying to find out the water leakage rate from a closed loop system through pressure drop.
or if someone knows the formula for how much water input is required to increase pressure that would also work.
the system volume is 1200Litres
Pressure drop is 5bar to 4 bar in 90...
Hi clever people
I am new here and hoping a couple of you smart people can help me. Im also sorry if this is a really silly question.
I am trying to create a basic set up of an air to water heat pump system.
for example an 18kw heat pump requires min 0.7l/s with a pressure drop of 60kpa over...
