Air at STP flows into a pipe manifold of diameter D and length L at M<<1. The manifold has N exit ports of area a at regularly-spaced streamwise stations. The downstream end of the manifold is closed. Assuming that wall friction can be neglected, sketch the streamwise pressure profile in the manifold. Explain your reasoning.
Please be neat, clear and specific ... Thanks in advance.

- 3) Water at 20C° follow throw piping junction in the figure below. Entering section (1) at (0.0019m /sec). The average velocity at section (2) is (2.5 m/s). Apportion of the flow is diverted throw the shower head. Which contain (100 holes) of (1mm) diameter. The exit velocity from the exit shower head is 7.5 m/s assuming uniform shower flow estimate the diameter of section (2) (3) (2) (1)Q.3 A firm produces frozen fruits and vegetables, and a venturimeter is used in this process.In a certain step of the process, the cherries are introduced to the cold air stream at -12oC with a 3 in. pipe connected vertically to the throat of the venturimeter. Venturimeter is connected to a pipe 4 in. in diameter. If the air velocity in the throat is 5 times the terminal velocity of the cherries and the ratio of throat/pipe diameter is 0.6, what should be the flow rate of air? Assume that the density of cherries is 1200 kg/m3 and the average diameters are 12 mm. What should be the lay-out of the pipeline between venturimeter and freeze-dryer to prevent the striking of the cherries to the walls? Is there any settling possibility of the cherries at the exit of the venturimeter?In a pipe of diameter 300mm the center line velocity and the velocity at a point 100mm from the center, as measured by pitot tube are 2.4 m/s and 2.0 m/s respectively. Assume the flow in the pipe to be turbulent find: 1-Dischrge through the pipe,2-Coefficient of friction, 3 Height of roughness projections.Please do not waste my question solve with correct answers only.

- An oil flowing through a tube of diameter 50mm, specific gravity 0.7 with a velocity of 20m/sec. Its kinematic viscosity is 12.5 stoke, then the flow is (A) Laminar (B) Turbulent (C) Transition (D) RotationalMechanical-Energy Balance and Friction Losses. Hot water is being discharged from a storage tank at the rate of o.223 ft3/s. The process flow diagram and conditions are the same as given in Example 2.10-6, except for different nominal pipe sizes of schedule 40 steel pipe as follows. The 20-ft-long outlet pipe from the storage tank is 1-in. pipe instead of 4-in. pipe. The other piping, which was 2-in. pipe, is now 2.5-in. pipe. Note that now a sudden expansion occurs after the elbow in the 13-in. pipe to a 2}-in pipe.Industrial piping system Develop a flowchart of a hypothetical industrial piping system (or a real example), in which the fluid is water, explaining the processes and listing and quantifying the equipment (boilers, heat exchangers, flow valves, relief valves, traps, installed machinery, drains, vents...)
