Question: Which of the following is the correct formula for calculating the supercooled temperature of steam, when steam metastable expansion of steam takes place inside a steam nozzle. (T2 ? Supercooled temperature, T1 ? Inlet temperature of steam)

Options

A : \frac{T_2}{T_1} = (\frac{P_2}{P_1})^\frac{n}{n-1}

B : \frac{T_2}{T_1} = (\frac{P_2}{P_1})^\frac{n+1}{n}

C : \frac{T_2}{T_1} = (\frac{P_1}{P_2})^\frac{n}{n-1}

D : \frac{T_2}{T_1} = (\frac{P_2}{P_1})^\frac{n}{n-1}
