Air is flowing through a venturi meter whose diameter is 6.6 cm at the entrance part and 4.6 cm at the throat. The gage pressure is measured to be 84 kPa at the entrance and 81 kPa at the throat. A) Neglecting frictional effects, show that the volume flow rate can be expressed as: V = A21 2(P-P) P(1 – AA) B) Determine the flow rate of air. Take the air density to be 1.2 kg
