Assume f = 0.034 for all pipes and neglect minor losses.  The following are the properties of each pipe: Pipe 1 (Length=345 m, Diameter = 347 mm) Pipe 2 (Length=477 m, Diameter = 571 mm) Pipe 3 (Length=598 m, Diameter = 665 mm) Pipe 4 (Length=710 m, Diameter = 380 mm) Pipe 5 (Length=823 m, Diameter = 594 mm) Round your answer to 3 decimal places.

Fluid Mechanics Question An empirical equation for the velocity distribution in a horizontal, rectangular, open channel is given by u= umax(y/d)n where u is the velocity at a distance y feet above the floor of the channel.

Consider a hydraulic jack being used in a car repair shop, as in the figure. The pistons have an area of Ap= 0,8 cm? and A= 0.04 m2, Hydraulic oil with a specific gravity of 0.870 is pumped in as the small piston on the left side is pushed up and down, slowly raising the larger piston on the right side. A car that weighs 13,000 N is to be jacked up. At the beginning, when both pistons are at the same elevation (h= 0), calculate the force F+ in newtons required to hold the weight of the car. 1. What height of mercury column will cause a pressure of 680 kPa? Use sg of mercury equals to 13.6 2. Determine the pressure in a vessel of mercury, specific gravity 13.6, at a point 20 cm below the surface. Express the answer in kN/m2.

1. A rectangular channel has a contraction that smoothly changes the width to a minimum width of 1.5 f t (the throat). If the flow is critical at the throat, find the volume flow rate when the depth at the throat is 1.5 f t. 2. Water in an open channel of constant width flows over a bump of height 1 f t, as shown in Figure P10.10. What is the depth of the water Y2? Assume uniform flow of constant width with no losses.
