The value of h3 is determined from the state specified by T3, atmospheric pressure, and the composition of the exiting air–hydrogen mixture. This is accomplished through an appropriate call to REFPROP, i.e. (15) h 3 = h ( T 3, P A T M, Y 3) where Y3 represents the set of mass fractions for exiting air and hydrogen.
