- One side of the container has a 03-m square door that is hinged at its top edge. If the container is filled with water, determine the smallest force F that must be applied to the bottom edge of the door to keep it closed.In relation to the figure shown, the liquid is water (p = 1000 kg / m3). The gate is rectangular and rotates around "A". Determine the value of “y” so that the gate opens when the free surface of the water reaches the level shown.The truck carries an open rectangular container that is 3.9m wide, 3.0m deep and 5.0m long, contains oil of density 811kg/m³ to a depth of 2.1m. If it has a constant acceleration of 6.9m/s². Determine the total force(in kN) acting at the rear wall of the container.
- A tank contains a liquid of relative density 0.80. The height of the tank is 4, and the width of the tank is 2m. The tank is subjected to the acceleration of 5m/s^2 along a 30o inclined plane in the upward direction. Under this condition, there is no loss of liquid. determine the slope of free surface determine the pressure at presureThe 100cm radius cylinder weighs 3.1 KN and rest on the bottom of a container which is 1.5 meter long. Oil and water are poured into the left and right portion of the container to the depth of 0.8m and 1.4m respectively. Find the magnitude of the horizontal and vertical components of the force which will keep the cylinder touching the container at B.The cylindrical tank containing water accelerates upward with az = 3.5 m/s2 while it rotates about its vertical axis by n = 100 rpm. Determine the pressure at point A.
- Determine the pressure at a point 10 m below the free surface in a fluid that has a variable density in kilograms per cubic meter given the density equal to 450+ ah, in which a = 12kg/m^4 and h is the distance in meter measured from the free surface.A fish tank that contains 60 cm high water is moved in the cabin of elevator. Determine the pressure in kPa at the bottom of the tank when the elevator is moving upward with an upward acceleration of 3 m/s^2. ( With Free Body Diagram)Consider a body of arbitrary shape. If the pressure distribution over thesurface of the body is constant, prove that the resultant pressure force onthe body is zero.
- A tank of water 4 m deep receives a constant upwardacceleration a z . Determine ( a ) the gage pressure at the tankbottom if a z = 5 m 2 /s and ( b ) the value of a z that causes thegage pressure at the tank bottom to be 1 atm.Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb = ρairgVballoon, will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 85 kg each, determine the acceleration of the balloon when it is first released. Assume the density of air is ρ = 1.16 kg/m3 , and neglect the weight of the ropes and the cage.a fish tank that contains 60cm high water is moved in the cabin of elevator. Determine the pressure in kPa at the bottom of the tank when the elevator is stationary
