Question: Which of the following the correct formula for calculating the exit velocity of steam through nozzle considering the expansion to be metastable.
Options
A : C2 = \sqrt{2*\frac{n+1}{n-1}(P_1)(v_{g1}){1-(\frac{P_2}{P_1})^\frac{n-1}{n}}}
B : C2 = \sqrt{2*\frac{n-1}{n+1}(P_1)(v_{g1}){1-(\frac{P_2}{P_1})^\frac{n+1}{n}}}
C : C2 = \sqrt{2*\frac{n}{n-1}(P_1)(v_{g1}){1-(\frac{P_2}{P_1})^\frac{n-1}{n}}}
D : C2 = \sqrt{2*\frac{n}{n-1}(P_1)(v_{g1}){1-(\frac{P_2}{P_1})^\frac{n-1}{n}}}
