Consider a regenerative gas-turbine power plant with two stages of compression and two stages of expansion. The overall pressure ratio of the cycle is 9. Argon enters each stage of the compressor at 300 K and each stage of the turbine at 1200 K. Assuming constant specific heats, determine the minimum mass flow rate of argon needed to develop a net power output of 115 MW. The properties of argon at room temperature are cp = 0.5203 kJ/kg-K and k = 1.667. The minimum mass flow rate of argon is kg/s.

Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.
