- An inclined rectangular gate AB is constructed at the bottom of a vertical surface of an open dam as shown in the figure below. The gate is 2.5 m wide and 4.0 m long. What is the pressure force of water to the gate? Express your answer in kN.A 0.9 m diameter vertical cylindrical tank which is 1 m high and is open to the atmosphere contains water upto 0.3 m height. The tank is rotated about the centerline and the water level drops at the centre, while it rises at the edges. The angular velocity at which the bottom of the tank will be just exposed is _____ rad/s.Consider a cubical water tank with a side length of 3.5 m. The tank is half filled with water, and is open to the atmosphere. Now, a truck carrying this tank is accelerated at a rate of 7 m/s^2 on a flat road. The maximum vertical rise (in meters) of free surface of the water is ?"

Find thickness between to cylinder if it filled with oil has (0.3 pa.s) and internal cylinder moving down by (0.1 m/s).Consider a cubical water tank with a side length of 4 m. The tank is half filled with water, and is open to the atmosphere. Now, a truck carrying this tank is accelerated at a rate of 7 m/s^2 on a flat road. The maximum vertical rise (in meters) of free surface of the water is? only HANDWRITTEN answer needed ( NOT TYPED)Figure AB Cover rests on a flat surface. Cover 180 kg weight and 1.2 m wide. At what height is the water depth the lid won't open? find it. (glycerin density is 1260 kg/m3 , That density 1000 kg/m3 )
- The submerged sector gate AB shown in the figure is 1/9 of a circle of radius 4 m. The length of the gate is 10 m. Determine the horizontal component of water pressure acting on the gate.A gate with a mass of 45 kg is hinged at point A. The gate dimensions are a = 90 cm and b = 60 cm, and the angle between the horizontal is 45°. A counterweight of W is attached with a rod to balance the gate, as shown in the figure. If the length of the balancing rod is 90 cm and the vertical distance from point A to the free surface of the water is given as 30 cm, determine the required mass of counterweight to keep the gate closed.A circular tank with a diameter of 4.5m is filled with two immiscible fluids. Water to a depth of 3m andoil with a relative density of 0,9 to a depth of 2mDetermine the Hydrostatic force acting on the verticalside of the tank and the position of the centre of pressure from the oil-free surface.

The container for mixing is to rotate the axis. Find the depth of shedding (rad / s) that can be reached without draining the paint.A rectangular gate 1.4 m in base and 1.8 m high is placed on the face of the water reservoir, as shown in the figure. Its upper portion is hinged and the base is attached to a cylindrical buoy whose weight is 20 kg. The external diameter of the buoy is 2 m and the weight of the gate is 50 kg. The mechanism is such that the buoy will open the gate if water surface will rise higher than 4 m. What is the height of the buoy below the water surface?
