What is the formula to compute the efficiency of diffusers?(a) ηD = \(\frac {(\frac {p_{d_0}}{p_0})_{actual }}{(\frac {p_{0_2}}{p_{01}})_{normal \, shock \, at \, M_e}}\)(b) ηD = \(\frac {(\frac {p_{d_0}}{p_0})_{actual }}{(\frac {p_{0_2}}{p_{01}})_{oblique \, shock \, at \, M_e}}\)(c) ηD = \(\frac {(\frac {p_{0_2}}{p_{01}})_{normal \, shock \, at \, M_e}}{(\frac {p_{d_0}}{p_0})_{actual }}\)(d) ηD = \(\frac {(\frac {p_{0_2}}{p_{01}})_{oblique \, shock \, at \, M_e}}{(\frac {p_{d_0}}{p_0})_{actual }}\)This question was addressed to me in an international level competition.My question is taken from Compressible Flow through Diffusers in section Compressible Flow through Nozzles, Diffusers and Wind Tunnels of Aerodynamics |

Answer» Correct option is (a) ηD = \(\FRAC {(\frac {p_{d_0}}{p_0})_{ACTUAL }}{(\frac {p_{0_2}}{p_{01}})_{normal \, shock \, at \, M_e}}\) |
