Calculator Description
Fluid Forces Calculator v1
The fluid force calculator determines the forces imposed on a body moving through a fluid such as air or water

Fluid Force


Fluids generate a force on a body due to surface friction and their resistance to separate and flow around the body. This resistance is predominantly due to a combination of the viscosity of the fluid and the shape and surface texture of the body.

Such forces can induce significant stresses in the body or anything to which it may be attached. They also limit eternal acceleration resulting in a terminal velocity when the body is falling through the fluid under the influence of gravity.


The fluid forces calculator uses Morison’s equations for both of its calculation options;

Terminal Velocity; calculates the terminal speed of a body (e.g. a ball, brick, etc.) falling through a fluid (e.g. air, water, etc.) under the influence of gravity

Force on a Body (e.g. a beam, barrier, submarine, etc.); calculates the force induced on a body, along with its direction, due to its movement through a moving fluid.

Fluid Forces imports data from CalQlata’s, Waves, Volumes and Added Drag calculators
