Water flows in the bend shown in figure at a rate of 5 m3/s, and the pressure at the inlet is 650 kPa. If the head loss in the bend is 10 m, what will the pressure be at the outlet of the bend? Also estimate the force of the thrust block on the bend in the x direction required to hold the bend in place. Thrust block 60° D = 80 cm Expansion joint Plan view d = 50 cm

1. The rigid gate with 3m width is installed in order to control the water outflow as shown in the figure. The gate is hinged at point O and rests against a support at point B. Assuming that the weight of the gate as well as the friction at the hinge don't have significant effects, determine the following: Wate 4 m a. Determine forces (resultant forces). b. Locate the center of pressure for the hydrostatic forces (resultant forces). c. Required horizontal force, the gate closed. the magnitude of the hydrostatic Hing 3 m B A P in order to hold 2 m Atmosphere

Problem P68 (a) Determine the magnitude of the anchoring force needed to hold the horizontal bend and nozzle in place. The velocity at location 1 is known to be 2 m/s. The pressure at location 1 of the 300 mm diameter pipe is known to be 100 kPa. The discharge at section 2 is in the form of a free jet to the atmosphere. Ans: F = 8.345 kN 300 mm 160 mm Diameter Jet P₁ = 100 KPa Reducing Bend with Nozzle FRB/F

The laminar flow takes place between closely spaced parallel plates as shown in figure below. u > V y Ľ The velocity profile is given by u = v. The gap height h is 5 mm and the space is filled with oil (specific gravity = 0.86, viscosity μ = 2 x 10-4 N-s/m²). The bottom plate is stationary and the top plate moves with a steady velocity of v= 5cm/s. The area of the plate is 0.25 m². The rate of rotation of a fluid particles is given by
