Thermal

API recommends a 3/4"x1" valve for most systems. However, depending on the situation, calculations may be required. API gives a formula to use that is based on specific gravity heat capacity, and an expansion coefficient.
One note, if the heat that cause thermal expansion is above the boiling temperature of the fluid at the relief temperature, you will have vaporization. In that case, a 3/4"x1" will no longer provide adequate capacity.

Probably more than you ever wanted to know...
