Fluid flows at a velocity V through a horizontal pipe of diameter D. An orifice plate containing a hole of diameter d is placed in the pipe. It is desired to investigate the pressure drop, Ap, across the plate. Assume that Ap = f (D, d, p, V) wherep is the fluid density. Determine all possible z terms. Show ALL steps. (Figure shows a longitudinal profile section of the pipe). P1 P2 Use FLT Svstem ONLY Flow D

6. A plastic siphon hose with D = 1.2 cm and is L = 5.5 m used to drain water (15°C) out a tank. Calculate the velocity in the tube for the two situations given below. Use H = 3 cm and h = 1 cm. a. Assume the Bernoulli equation applies (neglect all head loss). b. Assume the component head loss is zero, and the pipe head loss is nonzero.

Note:hand written solution should be avoided.

An incompressible fluid is flowing at steady rate in horizontal pipe. From a section, the pipe divides into two horizontal parallel pipes of diameter (d, and d₂) (where d₁ = 4d₂) that run, for a distance of L each and then again join back to a pipe of the original size. For both the parallel pipes, assume the head loss due to friction only and the Darcy-weisbach friction factor to be same. The velocity ratio between bigger and smaller branched pipe is.
