Behaviour of accelerated object in fluid chamber with perforated bottom

[mac80]

I have a object which travels down a chamber filled with fluid with perforated bottoms. As the objects travel with constant velocity it will de-accelerate due to resistance provided by displacing fluid. Density of fluid is known as well as force pushing object.
I am neglecting the drag as OD of object is equal to ID of chamber so it will only force object out.

will only calculating change in acceleration over time with inertial resistance ? Intent is to calculate impact of object when it hit bottom of chamber. Any advise on how to approach this issue.

There are several approaches you can take to calculate the impact of the object when it hits the bottom of the chamber. One approach is to use the equations of motion to calculate the acceleration, velocity, and position of the object over time. You would need to know the force pushing the object, the mass of the object, and the density of the fluid in the chamber. With this information, you can calculate the acceleration of the object due to the inertial resistance of the fluid. This will give you an estimate of how quickly the object will decelerate as it moves through the chamber. Once you have estimated the velocity and position of the object at any given time, you can calculate the impact of the object when it reaches the bottom of the chamber. Alternatively, you could also use a numerical simulation to calculate the impact of the object. A numerical simulation will involve solving the equations of motion numerically, using a computer program such as MATLAB or Python. With a numerical simulation, you can determine the exact trajectory of the object as it moves through the chamber. This will allow you to accurately predict the impact of the object when it reaches the bottom of the chamber.
