The Mach number is proportional to this quantity raised to the one-half power.
The Mach number is proportional to this quantity raised to the one-half power. It's not volume, but this quantity times the derivative of pressure with respect to this quantity gives the bulk modulus. The kinematic viscosity is equal to the dynamic viscosity divided by this quantity. Porosity is equal to one minus the ratio of the "bulk" and "particle" versions of this quantity. The pressure term in the (*) Bernoulli equation is equal to the change in pressure divided by this quantity, causing the difference in pressure between two points in a static fluid to equal this quantity times "little g" times the height difference. The ratio of this quantity for a fluid to this quantity for water is the fluid's specific gravity. For 10 points, name this quantity equal to a material's mass divided by its volume.
