Hi please help: the Venturi tube shown may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of gasoline (density=750 kg/m^3) through a hose having an inlet (left side) radius of 2.0 cm and an outlet (right side) radius of 1.0 cm. The difference in pressure is measured to be P1-P2=1340 Pa What is the speed of the gasoline V1 (in m/s) at the inlet?
