3. A small fan engine (as shown in the figure) was tested and the incoming speed u1 was 100m/s. The inlet area is A1 = 0.1m-, and the exhaust speed

is uz = 200m/s.Assuming that the flow is accelerated by the fan and that the pressure and density are the same at the inlet and exit (and p= 12 kg/m), calculate the exit area A, Also calculate the thrust generated by this unit.
