Consider an open circuit wind tunnel as shown below. The fan draws

Consider an open circuit wind tunnel as shown below. The fan draws stationary air at atmospheric pressure through the collector (point 1). The velocity upstream of the collector is V_1 = 0 m/s and upstream of the fan it is V 3=27 m/s. The air density is p=1.21 kg/m^3. Evaluate the pressure upstream of the fan p 3 (at point 3) in Pa.
