The gradient of this quantity is greatest below a pycnocline.
The gradient of this quantity is greatest below a pycnocline. This quantity times the derivative of pressure with respect to this quantity gives the bulk modulus. Incompressible fluids have a constant value of it. For liquid water this quantity is maximized at 4 degrees Celsius. Every term in the Bernoulli equation except for the pressure is multiplied by this quantity. The pressure at the bottom of a pool is equal to the depth, times gravity, times this quantity. The ratio of this quantity for a given substance to that of water is the specific gravity. For 10 points, name this quantity, the ratio of mass to volume.
The gradient of this quantity is greatest below a pycnocline.
