A venturimeter is used to measure water flow rate of 7.5m^3/min. If pressure difference between the wide and throat sections of the venturi is 12.50 kPa, and the pipe diameter at the wide section is 20 cm, calculate the throat diameter. (Use density=1000 kg/m^3 and coefficient of discharge Cd=0.96).

Suppose air, with a density of 1.29 kg/m3 is flowing into a Venturi meter. The narrow section of the pipe at point A has a diameter that is 0.402 times the diameter of the larger section of the pipe at point B. The U-shaped tube is filled with water and the difference in height between the two sections of pipe is h = 1.96 cm. How fast is the air moving at point B?
