Question

The air standard efficiency of closed gas turbine cycle is given by (r_p = pressure ratio for the compressor and turbine)

(a) η = 1 – \(\cfrac{1}{(r_p)^{γ-1}}\)

(b) η = 1 – ( rp) ^{γ − 1}

(c) η = 1 – \(\left(\cfrac{1}{r_p}\right)^{γ-1/γ}\)

(d) η = (rp)^γ-1/γ - 1

Answer 1

(d) η = (rp)^γ-1/γ - 1
