A small industrial GT runs on a mixture of $CH4$ and $H2.$ The thermal output is $1MW$ and the nominal operating condition is as

follows: $=0\mathrm{.}7,$ volume ratio of $H2$ and $CH450$:$50.$ Calculate the air flowrate and the mass flow rates of $CH4$ and $H2.$

$($Note$)$ The lower heating value of $CH4$ and $H2$ is $50$ and $119\mathrm{.}9M\frac{J}{k}g,$ respectively
