Metre per second (U.S. spelling: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector), defined by distance in metres divided by time in seconds. The symbol is m/s, or equivalently, m s-1. ... SI derived units are part of the SI system of measurement units and are derived from the seven SI base units. ... Speed (symbol: v) is the rate of motion, or equivalently the rate of change of position, expressed as distance d moved per unit of time t. ... Scalar is a concept that has meaning in mathematics, physics, and computing. ... Jump to: navigation, search This article is about velocity in physics. ... The word vector means carrier in Latin; it is derived from the Latin verb vehere, which means to carry. ...

(every second) must be the same as the amount of air leaving the rotor area to the left, the air will have to occupy a larger cross section (diameter) behind the rotor plane.
With a wind speed of 8 metrespersecond we get a power (amount of energy persecond) of 314 Watts per square metre exposed to the wind (the wind is coming from a direction perpendicular to the swept rotor area).
v = the velocity of the wind measured in m/s (metrespersecond).
