The Venturi meter shown in the figure can be used as fluid flow meter. Suppose the device is used at a service station to measure the flow of the gasoline (density = 7.00 x 10^2 kg/m⁄ ^3) through a hose having an outlet radius of 1.20 cm. If the difference in pressure is measure to be P1 − P2 = 1.20 kPa and the radius of the inlet tube to the meter is 2.40 cm, find (a) the speed of the gasoline as it leaves the hose and (b) the fluid flow rate in cubic meters per second.
