In Fig., gate AB is 5 ft wide into the paper, and stopB will break if the water force on it equals 9200 lbf. Forwhat water depth h is this condition reached?

The U-tube in Fig.  is open at A and closed at D. Ifaccelerated to the right at uniform a x , what acceleration will cause the pressure at point C to be atmospheric? Thefl uid is water (SG = 1.0).

Q1: The U tube (in Fig.1) is open at (D) and closed in (A). What will be the pressure at point (A, B and C): 1- Uniform acceleration (az=10m/sec?) to the top only. 2- Uniform acceleration (ax =10m/sec²) to the right and (az=10m/sec") to the top. 0.6m 0.9m Fig.1

The iceberg idealization may becomeunstable if its sides melt and its height exceeds its width. InFig.  suppose that the height is L and the depth intothe paper is L , but the width in the plane of the paper isH , L. Assuming S =0.88 for the iceberg, fi nd the ratio H / Lfor which it becomes neutrally stable (about to overturn).

A tidal barrage is in the shape of a quarter cylinder of radius r=16m, as shown in the picture above. If the barrage is 13m wide and holds back water of density 1014kg/m³ to its full height, what is the magnitude of the vertical force on the barrage? Assume that the atmospheric pressure is constant. Give your answer in Kilo Newtons to the nearest whole number. Use an acceleration due to gravity of g=9.81m/s²

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

4.17 The torque T necessary to rotate a disc of radius R a distance h from a flat plate depends on the rotational speed w and the fluid viscosity p.. Relate T to the appropriate variables and fluid density, rho.

A pressurized tank of water is used to create a fountain, as illustrated. Assume that the water's free surface area in the tank is very large relative to the pipe's cross-sectional area, which is circu- lar with diameter d 1.0 cm. The small pipe bend has height = 10.0 cm. At the instant when 0.75 m, H = 2.5 m, and the gauge measures a pressure of Pgauge 20.0 kPa, the water spray reaches a height L above the pipe exit. h = = = Neglecting viscous effects, determine the height of the spray, L.
