Consider a regenerative Brayton cyclewith intercooling between two stages of compression and reheating between two stages of expansion. The overall pressure ratio of the cycle is 9. Air enters each stage of the compressor at 300K and each stage of the turbine at 1200K. Accounting for the variation of specific heats, determine the minimum mass flow rate of air needed to develop a net power output of 110MW.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.
