Temperature Pressure (TP) Relief Valve Conditions / Thermal Expansion of Water
Hello there everyone,
I have some concerns regarding formulations of temperature and pressure in hot water tanks / water heaters.
What Pressure Increase Do We Actually Observe in Water Heaters & Hot Water Heating Boilers?
Assuming we are dealing with a closed system.
What is the pressure change of water inside the tank when the temperature increase from 16°c to 99°c
Since the TP valve will trip at 99°c / 150 psi - will those conditions ever exist? Can you get 150 psi and 99°c?
This is confusing to me because it seems as though the valve will trip only at 99°c since it will reach that temperature way before the pressure getting to 150 psi..
How can we obtain some sort of pressure-temperature plot? or calculate the thermal expansion pressure due to a specific change in temperature?
If the system goes from 80 psi to 150 psi for example, what is the resultant change in temperature?
Once TP valve trips, how much water will be discharged?
