Problem 2 Water flows through a horizontal 45 degree bend with a 22-in dimeter at a rate of 20 ft³/s under a pressure of 15 lb/in². a. In the x-direction P₁ b. In the y-direction y κα F *P2, Fx F Neglecting the head loss in the bend, calculate the resisting force required to anchor this pipe bed: X

A concrete retaining wall is shown in the figure. The fill behind the wall has a unit weight of 100pcf whose active soil pressure may be assumed equivalent to a fluid pressure of 30psf per foot. The passive soil pressure may be assumed equivalent to a fluid pressure of 300 psf per foot. The live load surcharge behind the wall is equivalent to an additional of 2ft of fill. Unit weight of concrete is 150pcf. Consider 1 ft length of wall.Which of the following most nearly gives the total active pressure acting on the wall?
