Height — is the measurement of vertical distance, but has two meanings in common use. It can either indicate how tall something is, or how high up it is. For example one could say That is a tall building , or That airplane is high up in the sky . These… … Wikipedia
Gravity current — In fluid dynamics, a gravity current is a primarily horizontal flow in a gravitational field that is driven by a density difference, hence gravity currents also sometimes being referred to as density currents . Typically, the density difference… … Wikipedia
Metacentric height — Ship Stability diagram showing centre of gravity (G), centre of buoyancy (B), and metacentre (M) with ship upright and heeled over to one side. Note that for small angles, G and M are fixed, while B moves as the ship heels, and for big angles B… … Wikipedia
Human height — Tall redirects here. For other uses, see Tall (disambiguation). Human height is the distance from the bottom of the feet to the top of the head in a human body standing erect. When populations share genetic background and environmental factors,… … Wikipedia
Scale height — A scale height is a term often used in scientific contexts for a distance over which a quantity decreases by a factor of e. It is usually denoted by the capital letter H .For planetary atmospheres, it is the vertical distance upwards, over which… … Wikipedia
Orthometric height — The orthometric height is the distance H along a line of force from a given point P at the physical surface of an object to the geoid. Orthometric heights are what are usually used in the US for ordinary engineering work. Values for measured… … Wikipedia
