Question

In an ideal gas turbine plant, the maximum and minimum temperature are 1100 K and 294 K and the pressure ratio is 10. Due to new development in the field of materials available for blades, the maximum temperature allowed in the cycle can be increased to 1245 K keeping pressure ratio unchanged. The percentage gain in efficiency of the cycle is _______% ( Correct to decimal place)

Solution

The correct option is A 0
0
$n_{B r a y t o n} = 1 - \frac{1}{{(r_{p})}^{γ - 1 / Y}}$

$n_{B r a y t o n} \neq f (T_{max})$ and pressure ratio is constant.
