Consider a cryogenic liquid rocket engine using an expander cycle with liquid
hydrogen and liquid oxygen as the two propellants. The mass flow rate of
hydrogen
2Hm
into the combustion chamber is
32 kg/s , and the mass flow rate of
oxygen
2Om
into the chamber is such that
22
8HOmm =
. The combustion of
hydrogen and oxygen is at stoichiometry. Assuming that the rate of the forward
reaction is much larger than that of the reverse reaction, the rate of formation of
H2O is ________ kmol/s. (round off to the nearest integer)
