A pipe of inlet diameter 15+0 cm conveying 2 liters/s of water has bend of angle (θ =  90⁰) in horizontal plane. The outlet diameter is 10+ 0 cm. The inlet pressure is 15 N/cm2 . Find the resultant force exerted on the bend   do a sketch if needed

lower end of a string and is moving in a horizontal circle of radius R = 0.15 m at constant speed v = 0.51 m/s. The string has length l and negligible mass and makes an angle 0 with the vertical. The angle 0 is %3D m

The tank of water shown below is 15 cm wide into the paper. The tank is accelerated in rigid- body motion at 9 m/s² in x-direction (right) and 2 m/s“ in z-direction (upwards). Assume no spilling. (a) Show with sketch what will happen to surface point B. (b) Find the angle 0 and the new water depth (height) of side AB. (c) Calculate the water force on wall AB. 3 Given: Specific Weight of Water, Ywater = 9790 N/m', Draw sketch and show all calculations. B 20 cm Water at 20°C 36 cm

The face of a dam is a vertical rectangle of height 100 ft and width 200 ft (Figure 6.8.5a). Find the total fluid force exerted on the face when the water surface is level with the top of the dam.

3.14. Find the vorticity in polar coordinates for the following velocity com- ponents (a) v=rsin 0, ve = 2r cos 0 (b) v = cos 0, 11=0

If a hole is drilled at the bottom of a full bucket of water of height. H 60 meter what is the second velocity and first if we have pressure 1 in the air is 103 kpa and pressure 2 760pa (proof the equation you used to solve it ) Kindly re-draw the diagram.
