The RB 207 Turbofan engine used in commercial transport "jumbo" aircraft produces a static thrust (i.e. in still air) of 47, 500 lbf with a mass flow of 1383 lbm/s The inlet to the turbofan has an area of 53.3 ft^2. The inlet air density is 0.075 lbm/ft^3 (a) calculate the exit velocity in f t/s. (b) Calculate the inlet velocity to the fan assuming constant density.
