    A venturi meter is a device for measuring the speed of a fluid within a pipe. The drawing shows a gas flowing at a speed v2 through a horizontal section of pipe whose cross-sectional area A2 = 0.0700 m2. The gas has a density of ϝ = 1.30 kg/m3. The Venturi meter has a cross-sectional area of A1 = 0.0300 m2 and has been substituted for a section of the larger pipe. The pressure difference between the two sections is...

    K, tugi +(li-P)= K2 + Ug2 0 Part B A situation that can be represented by by the qualitative Bernoulli bar chart shown in the figure (Figure 1) is as follows: The flow speed of water in a constricted section of a pipe having cross-sectional area A1 is v1. In the regular section of the pipe, the cross-sectional area is A2 and the flow speed is v2. Determine the pressure in a constricted section of a pipe if the pressure...

    Water is flowing through a 10-cm-diameter water pipe at a rate of 0.1 m/s. Then, a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water as it exits the diffuser to atmospheric pressure, as shown in the given figure. Disregarding frictional effects, determine the force exerted on the bolts due to the water flow. Take the density of water to be 1000 kg/m3 -t- d 10 cmm D = 20...

    Water flows through a pipe as shown below. A1 and A2 have equal radii of r1=r2=.05 m. A3 has a radius r3=.15 m. The section of the pipe between A1 and A2 is made that it has an unknown cross sectional area. The initial velocity of the fluid and pressure of the fluid and pressure at location 1 is 10 m/s and 6.01x10^5 N/m^2 respectively. (Water has a density of 1000 kg/m^3 also treat the water as ideal i.e. negligible...
