It isn't a solid or gaseous relationship. It has no boundaries and may mix with other fluids. Also you can dissolve stuff in it.
Yeast is the relationship with capacity and fluid ounces
As viscocity increases fluid flow decreases ....in other words, the relationship is inverse.
There are 16 fluid ounces to one pint.
Archimedes first stated the relationship between buoyant force and weight of a displaced fluid.
When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.
Daniel Bernoulli, a Swiss mathematician. Bernoulli's principle states that as the speed of a moving fluid increases, the fluid's pressure decreases.
Archimedes.
linear
A relationship between fluid-flow systems in which corresponding fluid velocities and velocity gradients are in the same ratios at corresponding locations.
Viscosity is constant to the flow of the fluid.
Fluid ounce is an old-fashioned unit, used to measure volume, or capacity.
The relationship between radius and fluid flow rate is inversely proportional. As radius goes down, fluid flow rate goes up. The highest fluid flow rate will be at the lowest radius.
