MHTB Feed and Vent Systems Steady State Analysis Purpose: 

MHTB Feed and Vent Systems Steady State Analysis Purpose Atmosphere LH2 Supply Tank MHTB Tank Spraybar # of orifices = 4008 Dorf = 0.043 in Feed System Vent System D = 4” D = 3” D = 6” D = 8” D = 12” Using GFSSP Simulate steady state operation of the Feed System and predict LH2 flowrates for different Supply Tank pressures. Simulate steady state operation of Vent System and predict GH2 flowrates for different MHTB tank ullage pressures.
