Regeneration, Reheat, and Compression with Intercooling

An air-standard Brayton cycle produces 10 MW of power. The compressor and turbine isentropic efficiencies are both 80%. Operating data at principal states in the cycle are given in the table below. The states are numbered as in Fig. 9.9.

(a) Fill in the missing data in the table and sketch the T–s diagram for the cycle.

(b) Determine the mass flow rate of air, in kg/s.

(c) Perform a full accounting for the net rate of exergy increase as the air passes through the combustor.

Let T₀ = 300 K, p₀ = 100 kPa.
