Question

The figure below shows a section of a horizontal pipe in which a nozzle-sleeve Ls inserted. The pipe has a square cross-section with a sidelength of ap = 10cm. and the nozzle sleeve introduces a smooth transition that reduces this sidelength to aN = aP/2. A mercury manometer (rho m = 13.6 rho) is connected to the pipe as shown and gives a reading of = 6.1 cm. Effects of friction at the wall can be neglected. Figure 5: Pipe with nozzle-sleeve Determine the flow rate in the square cross-section pipe. Q. Determine the headless associated with the nozzle-sleeve in the pipe. Determine the force exerted by the flow on the nozzle-sleeve. (HINT: Since you can calculate the pressure difference between sections 1-1 and 3-3. you can obtain the force by analyzing the control volume between these two sections).

Explanation / Answer

plzz rate me first :) E=y2 + v2^2/2g energy equaction V1=V2 A1*V1=A2*V2 ; A1=2A2 V1=2V2 Get V and solve rest part which is very easy
