$9-92$E A simple ideal Brayton cycle uses helium as the working fluid, operates at $12$ psia and $60$F at the compressor inlet, has a pressure ratio of $14,$ and a maximum cycle temperature of $1300$F$.$ How much power will this cycle produce when the helium circulation flow through the cycle is $100$ lbm$/$min$?$ Use constant specific heats at room temperature.

$9-93$E Repeat Problem $9-92$E when the isentropic efficiency of the turbine is $95$ percent.
