Question B12:
Air is flowing through a venturi meter, illustrated in Figure B12 whose diameter is 15
cm at the entrance and 10 cm at the throat. The gauge pressure is measured to be
100 kPa at the entrance and 95 kPa at the throat. Neglecting frictional effects,
determine the flow rate of air. Air density can be taken to be 1.2 kg/m$^3$.
