3 Hydrostatic Force Tutorial Solution

Liquid pressure. Known :. Wanted: liquid pressure. Solution :. Pipe U. A U pipe is initially filled with water than on one pipe filled with oil, as shown in the figure below. If the height of oil is 8 cm and the height of the water is 5 cm, what is the density of oil? Wanted : density of oil. A U pipe was first filled with kerosene then added water.

If the mass of kerosene is 0. Determine how much water should be added so that the height difference of the kerosene surface is 15 cm. Wanted : Volume of water. The height of water h 2 :. Volume of water :. The correct answer is C. If the height of glyserin is 4 cm, determine the height difference of both columns of the pipe. Wanted: The height difference of both columns of the pipe. The height of the column of the pipe h 1 :. The correct answer is A.

The sectional area along the pipe is the same, that is 1 cm 2. Someone blows on one end of the foot of the pipe so that the surface of the water at the other foot rises 10 cm from its original position. Change all units to the International system. Wanted : Force F acted by the person.

The correct answer is B. A Y-shaped tube is inserted upside down so that the left foot and right foot are immersed in two kinds of liquid. After both feet are immersed in the liquid, then the top of the Y pipe is closed with the finger and pulled upwards, so that the two legs of the Y pipe are filled with a column of different high-density liquids. If the density of the first liquid is 0. Wanted : T he height difference between the two liquid columns on U pip e. T he height of the higher liquids h 2 :.

The correct answer is D. Buoyant force. A stone with the volume of 0. Acceleration due to gravity is 10 m s What is the buoyant force? Wanted: buoyant force F A. The equation of the buoyant force :. A block of ice floa t in the sea as shown in the figure below. The density of sea is 1. If the density of the object is 0. Wanted: the density of the liquid x. The density of the liquid is kg m 3. Wanted : The d ensity of wood x.

The distance between the two troughs of the water surface waves is 20 m. An object floats on the surface of The tension force of the rope is An object vibrates with a frequency of 5 Hz to rightward and leftward.

hydrostatic pressure and pressure at depth equation

Hydrostatic force on submerged bodies 1. A vertical rectangular gate, 1. Determine the total resultant force acting on the gate and the location of c. An inclined rectangular gate 1. An inclined circular with water on one side is shown in the fig. Gate AB in the fig.

Thus in a fluid under gravity, pressure decreases linearly with increase in height. Derivation of Formulas Not required for exam. The figure shown below is an inclined plane surface submerged in a liquid. Forces on a inclined plane surface. The plate weighs N. Case 1: Liquid is above the curve surface. The vertical component of the hydrostatic force is downward and equal to the volume of the real liquid above the submerged surface.

Pressure is commonly defined as force per unit area. But in liquids, the column of liquid exerts a constant force downward due to its weight. The pressure exerted by a column of liquid is called hydrostatic pressure. This force due to the liquid's weight can be computed using the liquid's density and height. This is the reason why hydrostatic pressure has a different formula than pressure in solids. Hydrostatic pressure can be computed by multiplying the density of the fluid by the acceleration due to gravity and the depth. In symbols.

When a fluid either liquid or in gas is at rest or in equilibrium, it exerts a force to any surface in contact with it, such as walls of a container. While fluid as a whole is at rest, the molecules that make up the fluid are in motion; the force exerted by the fluid is due to molecules colliding with their surroundings. To feel that liquid exerts pressure try to stop the liquid flowing out of a vessel by pressing finger again the hole.

In this section we are going to submerge a vertical plate in water and we want to know the force that is exerted on the plate due to the pressure of the water. This force is often called the hydrostatic force. We are going to assume that the fluid in question is water and since we are going to be using the metric system these quantities become,. The second formula that we need is the following.
