. A horizontal pipe with a varying cross section. A liquid with a density of 1.65 g/cm' flows from left to right in the pipe, from larger to smaller cross section. The left side's cross-sectional area is 10.0 cm', and while in this side, the speed of the liquid is 2.81 m/s, and the pressure is 1.20 X 105 Pa. The right side's cross sectional-area is 3.50 cm. (a) What is the speed (in m/s) of the liquid in the right side (the smaller section)? (Enter your answer to at least three significant figures.) b) What is the pressure (in Pa) of the liquid in the right side (the smaller section)? The 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 gasoline (p = 7.00 x 102 kg/m3) through a hose having an outlet radius of 1.49 cm. The difference in pressure is measured to be Pi - P2 = 1.60 kPa and the radius of the inlet tub to the meter is 2.98 cm (a) Find the speed of the gasoline as it leaves the hose. m/s (b) Find the fluid flow rate in cubic meters per second. m3/s
