Thermodynamics Mech3001 - Week 9 - Problem 2 (9.86)

A gas turbine power plant operates on the simple Brayton cycle with air as the working fluid and delivers 32 MW of power. The minimum and maximum cycle temperatures are 310 K and 900 K and the pressure of the air at compressor exit is 8 times the value of the compressor inlet. Assuming an isentropic efficiency of 80% for the compressor and 86% for the turbine. Accounting for the variation of the specific heats with temperature, determine the mass flow rate of air through the cycle

Answer: a) 786.6 kg/s

This video helped a lot. Although, your first interpolation gave a value that's bigger than the two parent values so...I think you should check it again
