Problem $10\mathrm{.}089$E $-$ Simple Ideal Brayton Cycle with Variable Specific Heats in Imperial Units

A simple ideal Brayton cycle with air as the working fluid has a pressure ratio of $10.$ The air enters the compressor at $520$ R and the turbine at $1,900$ R$.$ Account for the variation of specific heats with temperature. Use data from the tables containing the ideal gas properties of air.

Problem $10\mathrm{.}089$E$.$a $-$ Compressor exit temperature in ideal Brayton Cycle

Determine the air temperature at the compressor exit.

The air temperature at the compressor exit is $$ R$.$
