3 cards from this section. Quick, good the night before a test.
What happens to fluid pressure as depth increases?
Think about swimming in a pool.
What is the formula for calculating the resultant force on a horizontal surface?
Recall the relationship between pressure and area.
What is the relationship between pressure and depth in a fluid?
Consider how deep you go while swimming.
Is the buoyant force on a submerged object equal to its weight?
Think of a fully submerged object.
A submerged rectangular gate 2m wide and 3m tall is located 5m below the surface of a water tank. Calculate the total force acting on the gate and the position of the center of pressure.
Use the integration of moments to find the center of pressure location.
In a fluid with a density of 1000 kg/m^3, determine the buoyant force acting on a sphere with a radius of 0.5m fully submerged under the fluid.
Don't forget to calculate the volume of the sphere first.
