How do you calculate the pressure on the base of a circular water tank of 3m2 base area and 2.5m deep if it was filled with water?
Pressure is equal to force divided by area (F/A). You already know that the area is 3m2, so now you just have to find out the force of the water on the base of the tank. First of all, you need to work out how much water there is, so you can determine it's mass and from this how heavy it is in the tank (this is the force - the waters own weight).
The volume of the water tank is Area times height (V = A * h). So the volume of this water tank is 3*2 = 6m3. Now, every m3 of water has a mass of 1 kg, so in this tank we have 6 * 1kg = 6kg of water. The weihgt of the water (force towards ground) is its mass times the acceleration due to gravity (what's holding your feet to the ground), as given by Newton's second law. So the water's weight (or force on the bottom of the tank) is 6 * 9.8 (acceleration due to gravity = 9.8 ms2) = 58.8 Newtons.
And now we work out pressure... Pressure = force/area = 58.8 N/3m2 = 19.6 N/m2
Hope that helps

How can I calculate water pressure in a closed system?
To calculate water pressure in a closed system, you can use the formula: Pressure Force/Area. This means that pressure is equal to the force exerted on the water divided by the area over which the force is applied. By knowing the force and the area, you can calculate the water pressure in the closed system.

How do you calculate the water pressure in psi?
To calculate water pressure in pounds per square inch (psi), you can use the formula: pressure force / area. This means that you divide the force exerted by the water on a surface by the area of that surface. The result will give you the water pressure in psi.

What is the pressure inside an inverted hollow cylinder in water and how to calculate it?
The pressure inside an inverted hollow cylinder in water is equal to the pressure at the depth of the cylinder's centroid multiplied by the specific weight of water. To calculate it, use the formula: pressure = (specific weight of water) * (depth of centroid of cylinder).
What is the water pressure formula and how can it be used to calculate the pressure in a given system?
The water pressure formula is P gh, where P is the pressure, is the density of water, g is the acceleration due to gravity, and h is the height of the water column. This formula can be used to calculate the pressure in a given system by plugging in the values for density, gravity, and height of the water column.
How do you calculate water pressure in a closed system?
To calculate water pressure in a closed system, you can use the formula: Pressure Force/Area. This means that pressure is equal to the force applied on the water divided by the area over which the force is distributed. This calculation helps determine the amount of pressure exerted by the water within the closed system.
How do you calculate total pressure of water?
The total pressure of water is calculated by adding the atmospheric pressure to the pressure due to the depth of the water column using the formula: total pressure = atmospheric pressure + (density of water × acceleration due to gravity × depth of water).
Why does a balloon change shape when filled with water?
The elasticity of the balloon's material allows it to expand and take on different shapes when filled with water. As the balloon fills with water, the pressure from the water pushes against the sides of the balloon, causing it to stretch and change shape.
How to calculate water pressure at depth?
To calculate water pressure at a certain depth, you can use the formula: Pressure density of water x gravity x depth. The density of water is typically 1000 kg/m3, and gravity is 9.81 m/s2. Multiply these values by the depth in meters to find the water pressure in pascals.
