A small high$-$speed turbine operating on compressed air produces a power output of $0\mathrm{.}1$ hp$.$ The inlet state iS $50$ psi, $120$ F$,$ and the exit state is $14\mathrm{.}7$ psi, $-20$ F$.$ Assuming the velocities to be low and the process to be adiabatic, find the required mass flow rate of air through the turbine.a$)3\mathrm{.}21$bm$/$hr b$)5\mathrm{.}3$ Ibm$/$hr c$)7\mathrm{.}61$bm$/$hr d$)10\mathrm{.}61$bm$/$hr
