methane gas enteres a steady flow steady state boiler

and burns with 140% theoretical hydrogen peroxide

H2O2 gas which acts as the oxidizer. the methane enters

at 25C(degree celcius) and 1 bar and the hydrogen peroxide

enters at 120C (degree celcius) and 1 bar; for constant

pressure assume cp= 1.267 KJ/Kg.K . Water is heated

at a constant pressure of 8MPa, entering

at 75C (degree celcius) and

exiting at 470C (degree celcius). the mass flow rate

of water is 3.7x10^5 Kg/hour. 92% of the thermal energy

supplied by the combustion process heats the water

and the remainder leaves the boiler and is lost to the

enviroment. What is the volumetric flow rate of

methane in m^3 / hour
