Question
(a) Derive an expression for the efficiency of a jet striking a moving curved vane at centre of the vane. (10)
(b) Drag force $F$ on a high speed aircraft depends on the velocity of flight $V$, the characteristic geometrical dimension of the aircraft $L$, the density $\rho$, viscosity $\mu$ and isentropic bulk modulus of elasticity $E_s$ of ambient air. Using Pi theorem, find out the independent dimensionless quantities which describe the phenomenon of drag on the aircraft. (10)
