In a convergent divergent nozzle, the velocity at throat of nozzle is given by Where p1 = initial entry pressure, v1 = initial entry specific volume and n = isentropic index of expansion.

\(V = {\left[ {\frac{{2n{p_1}{v_1}}}{{n - 1}}} \right]^{\frac{1}{2}}}\)

\(V = {\left[ {\frac{{2n{p_1}{v_1}}}{{n + 1}}} \right]^{\frac{1}{2}}}\)

\(V = {\left[ {2n{p_1}{v_1}} \right]^{1/2}}\)

\(V = {\left[ {n{p_1}{v_1}} \right]^{\frac{1}{2}}}\)

In a convergent divergent nozzle, the velocity at throat of nozzle is given by Where p1 = initial entry pressure, v1 = initial entry specific volume and n = isentropic index of expansion. Correct Answer \(V = {\left[ {\frac{{2n{p_1}{v_1}}}{{n + 1}}} \right]^{\frac{1}{2}}}\)

A nozzle is passage of smoothly varying cross-section by means of which the pressure energy of working fluid is converted into kinetic energy.

Convergent-Divergent nozzle: In a convergent divergent nozzle the cross-section of the nozzle first decreases and then increases.
