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 ṁH2 into the combustion chamber is 32 kg/s, and the mass flow rate of oxygen ṁO2 into the chamber is such that ṁO2/ṁH2 = 8. 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)
