Safety valve calculation
Thread Content
How is the discharge area of the safety valve for a storage tank containing mixed gases such as hydrogen and oxygen calculated? Is it calculated by using the adiabatic coefficients, molar masses, critical temperatures, and critical pressures of hydrogen and oxygen respectively, according to formulas B.5 or B.6 in GB150.1-2011? For hydrogen and oxygen separately, and then the sum of these values is taken to determine the required venting area?
It should be possible to calculate the required area for each voltage division separately and then add them together.
