Pressure Increase Formula
For the life of me I cannot find my math on this. I know it's pretty simple but I cannot easily find it on the internet or in my head. I am trying to figure out the pressure increase in a hot water. I know that is the science method. I did preform real world calculation thought too. I was curious about it all and I put a bump gauge on my water heater for approximately a month. I am on a drilled well with a 40/60 switch in place. My system is then 'closed' due to the softener and filters in place. My spike needle measured around 90PSI. So is there a formula to enter incoming psi, water temp in, water temp hi-limit and water volume to determine the potential pressure increase on the system? I believe the major of water heater failures where I come from (over 95% electrical tank style) are due to pressure build up on the tank and anode rods not being maintained. I am on a well but most are on a regional water supply that has good water quality.
