Flying Circus of Physics A venturi meter is used to measure the flow speed of a fluid in a pipe. The meter is connected between two sections of the pipe (see the figure below); the cross-sectional area A of the entrance and exit of the meter matches the pipe's cross-sectional area. Between the entrance and exit, the fluid flows from the pipe with speed V and then through a narrow "throat" of cross-sectional area a with speed v. A manometer connects the wider portion of the meter to the narrower portion. The change in the fluid's speed is accompanied by a change Ap in the fluid's pressure, which causes a height difference h of the liquid in the two arms of the manometer. (Here Ap means pressure in the throat minus pressure in the pipe.) Let A equal 3-a. Suppose the pressure p₁ at A is 3.0 atm. Compute the values of (a) the speed V at A and (b) the speed v at a that make the pressure p2 at a equal to zero. (c) Compute the corresponding volume flow rate if the diameter at A is 4.5 cm. The…

The figure shows the widening of a pipe in which the velocity of the liquid in the section with the smallest diameter is 15 m / s. If the minor diameter is approximately equal to one-third of the major diameter, determine the velocity of the liquid (in m / s) in the section with the largest diameter.
