![]() Where Pavg is the average pressure on the curved surface, A is the area of the curved surface, and θ is the angle between the normal to the curved surface and the horizontal direction.62. The weight of the fluid is equal to its mass times the acceleration due to gravity. The pressure due to the fluid is equal to the weight of the fluid divided by the area. Find the force acting on the side with the greatest depth in kN. Determine the amount of water spilled out when the tank is accelerated horizontally at 2.45 m/s2 in a direction parallel with its longest side in m3. ![]() This can be calculated using the formula: The pressure at the bottom of the container is due to the pressure of the atmosphere (p 0) plus the pressure due to the weight of the fluid. An open horizontal tank 2 m high, 2 m wide and 4 m long is full of water. (b) The magnitude of the torque exerted by the water about the. ![]() The horizontal force on this half is the difference between the forces exerted by these pressures on the curved surface. (a) The magnitude of the force the water exerts on the hatch is F 1 2 g w h 2 d h. Therefore, the pressure at the bottom is: When it is filled to a height of 2.5 meters, calculate the force in Newtons exerted on its base. In the vessels with inclined sides, you have the pressure working on the sides, that has a vertical component, down (first vessel) or up (third vessel). An open-topped cylindrical tank has a horizontal circular base 3 meters in diameter. But total force (weight) must be the same. Since the bulge is semi-circular, we can divide it into two halves and consider the pressure distribution on each half separately.įor the left half, the depth of the point at the bottom of the bulge is R, and the depth at the top of the bulge is R + 4. The Pressure (Base area) is different as you said. ![]() Where ρ is the density of water, g is the acceleration due to gravity, and h is the depth of the point below the water surface. The pressure at any point on the curved surface is given by the formula: To find the horizontal force exerted by the water on each bulge, we need to consider the pressure distribution on the curved surface. ![]()
