For me and dealing with natural gas, static pressure is my gas supply pressure to the unit while it’s not running. My dynamic pressure is how much gas is in the line when the boiler is running. I want to know the difference between the two when I’m at full fire. I imagine it works pretty much the same with air and fluid pressures.
