Question:-
The critical pressure ratio for maximum discharge through a nozzle is given by
Option (A)
{(n+1)/2}n/(n-1)
Option (B)
{2/(n+1)}n/(n-1)
Option(C)
{(n+1)/2}(n-1)/n
Option(D)
{2/(n+1)}(n-1)/n
Correct Option:
(B)
Question Solution:
(P*/P0) = {2/(k+1)}k/(k-1)
(T*/T0) = {2/(k+1)}
(r*/r0) = {2/(k+1)}k/(k-1)
