The flow of water from a reservoir is controlled by an L-shaped gate hinged at point A, as shown in the figure. The mass of the weight at B (a = 4 m to the right of A, b = 3 m above the base) is 5125 kg. If the gate opens when the water height is 1.75 m above the base, determine the width (in meters, not showing) of the gate.
The Super Soaker XP30 is a marvel of hydraulic dispersion weaponry. By pumping on the handle, you charge the chamber to high pressure. The pressure is maintained until you pull the trigger at which point the water (? = 1000 kg/m3) is released at high velocity.You have charged your pressure chamber to an absolute pressure of P1 = 697500 Pascals, much higher than today's outside air pressure of 101300 Pascals. The pressure chamber is location at a height of y1 = 0.103 meters above the exit point. The exit point has a small opening with radius r = 0.0033 meters.Determine all the following:The velocity at which the water exits the Super Soaker: v2 = m/sThe mass flow rate through the exit: kg/secThe volume flow rate through the exit: m3/secNOTE: You may treat the water chamber as a "tank" and approximate the water velocity there to be zero.
An open cylindrical container of radius R with a thin liquid layer of density p at the bottom, is rotating at a constant angular velocity w. As a result of the rotation, the liquid is displaced clearing a circular area at the bottom of the container or radius R/2. Determine the height of the liquid, H, on the cylindrical wall. R/2
Water fills the pipe AB such that the absolute pressure at A is 450 kPa . The inner diameter of the pipe is 55 mm . The density of the water is 1000 kg/m³. Acceleration due to gravity is 9.81 m/s². (Figure 1) Figure B 0.3 m 0.4 m If the atmospheric pressure is 101 kPa, determine the resultant force the water and surrounding air exert on the cap at B. Express your answer to three significant figures and include the appropriate units.

Milk with a density of 970 kg/m^3 is transported on a level road in a 9-m long, 3-m diameter cylindrical tanker. The tanker is completely filled with milk, i.e., no air space in the tank. If the truck is accelerating from a stop signal at 7.0 m/s^2 to the left, determine the pressure difference between the maximum and minimum pressures in the tank. Depict on the figure the location of the minimum and maximum pressures in the tank. min. 9m 3m
