- the property or state of being permeable.
- a measure of the change in magnetic induction produced when a magnetic material replaces air, expressed as a coefficient or a set of coefficients that multiply the components of magnetic intensity to give the components of magnetic induction.
- the capability of a porous rock or sediment to permit the flow of fluids through its pore spaces.
- the rate at which gas is lost through the envelope of an aerostat, usually expressed as the number of liters thus diffused in one day through a square meter.
- the capacity of a space in a vessel to absorb water, measured with reference to its temporary or permanent contents and expressed as a percentage of the total volume of the space.
- the state or quality of being permeable
- a measure of the response of a medium to a magnetic field, expressed as the ratio of the magnetic flux density in the medium to the field strength; measured in henries per metre
- the rate of diffusion of a fluid under pressure through soil
- the rate at which gas diffuses through the surface of a balloon or airship, usually expressed in litres per square metre per day
