Fluid Pressure & Force Calculus 2

• Gon
In summary, a marine biology observation pod is being designed with submerged windows of various sizes and shapes. The task is to calculate the total force exerted on each window, taking into account the density of water at 1000 kg/m^3. Integration is suggested as a possible method to solve this problem, and there is a discussion about water pressure varying with depth and its effect on the windows. One person is unable to solve for the final answer of 11099.9N for force F and asks for assistance in solving it using integration.

I'm not sure if I'm doing it in right way, do I need to use integration to calculate the total force?

How does the water pressure vary with depth ?

Is the water pressure acting on the windows varying with depth ?

YES

I solve all of them except F and the professor said the final answer should be 11099.9N but I didn't get that

So please show us what you did using integration to solve F (so we can see where to help).

1. What is fluid pressure?

Fluid pressure is the force per unit area that is exerted by a fluid on its surroundings. It is caused by the constant collisions of fluid molecules with the walls of a container or other objects in the fluid's path.

2. How is fluid pressure calculated?

Fluid pressure can be calculated using the formula P = F/A, where P is pressure, F is force, and A is the area over which the force is applied. In fluid pressure calculations, the force is typically the weight of the fluid and the area is the cross-sectional area of the container or object.

3. What is the difference between absolute and gauge pressure?

Absolute pressure is the total pressure exerted by a fluid, including atmospheric pressure. Gauge pressure, on the other hand, is the difference between absolute pressure and atmospheric pressure. It is often used in engineering and physics calculations.

4. How does fluid pressure change with depth?

According to Pascal's principle, the pressure in a fluid at rest increases with depth. This is because as depth increases, the weight of the fluid above increases, resulting in a greater force and therefore a higher pressure.

5. How is fluid force calculated?

Fluid force can be calculated using the formula F = P x A, where F is force, P is pressure, and A is the area over which the force is applied. This formula can be used to calculate the force exerted by a fluid on a surface or object, such as a dam or a submerged object in a river.
