he Venturi tube shown in the figure below may be used as a fluid flowmeter. Suppose the device is used at a service station to measure the flow rate of asoline \( \left(\rho=7.00 \times 10^{2} \mathrm{~kg} / \mathrm{m}^{3}\right. \) ) through a hose having an outlet radius of \( 1.60 \mathrm{~cm} \). The difference in pressure is measured to be \( { }_{1}-P_{2}=2.00 \mathrm{kPa} \) and the radius of the inlet tube to the meter is \( 3.20 \mathrm{~cm} \). (i) (a) Find the speed of the gasoline as it leaves the hose. Your response differs from the correct answer by more than \( 100 \% . \mathrm{m} / \mathrm{s} \) (b) Find the fluid flow rate in cubic meters per second. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. \( \mathrm{m}^{3} / \mathrm{s} \)
