Water expansion & pressures
Posted: Sun Feb 25, 2018 5:20 pm
Hi All
Anyone any experience with water expansion rates and pressures. Am trying to workout if the expansion tank is large enough following the fitting of a much larger radiator
If the fluid in the cooling system rose from zero degrees to 90 degrees (cooling system full to brim of fluid) how much fluid would it push into the expansion tank. System holds 7.5 litres of fluid and rad cap is 1,3 bar
Have been doing some experiments today where I pumped cooling system up to 19psi at about minus 3 degrees this morning and over the day it rose to 21 psi but ambient temp only made it to about 4 degrees.
So in simple terms if a can could hold 7.5 litres of fluid. and was heated from zero to 90 degrees what would the pressure be inside the can?
