Why does intercooling reduce compressor work?

Compressor work W ∝ T₁ (inlet temperature). Intercooling reduces temperature between stages, reducing work for subsequent stages. Isothermal compression is the minimum work limit; intercooling approaches this.

What is the back work ratio in gas turbines?

Back work ratio = W_compressor/W_turbine. For gas turbines: 40-80% (high back work). For steam turbines: <1% (pump work is small). High back work makes gas turbines very sensitive to component efficiencies.

How does compression ratio affect temperature rise?

T₂/T₁ = (P₂/P₁)^((γ-1)/γ). For air (γ=1.4) with P ratio 10:1: T₂/T₁ = 10^0.286 = 1.93. Starting at 300K, compressed air exits at 579K, or 300°C, for ideal compression.
