Lighting power density (LPD) is defined as the total amount of lighting power, in watts, provided to a given floor area, in square feet. A conventional general office lighting design has an LPD around 1.2 W/ft2, while an optimized design can be 0.8 W/ft2 or below.
In electromagnetism, charge density is a measure of electric charge per unit volume of space, in one, two or three dimensions. More specifically: the linear, surface, or volume charge density is the amount of electric charge per unit length, surface area, or volume, respectively.The respective SI units are C Â· m â1, C Â· m â2 or C Â· m â3.ontinuous charge distribution. The volume charge density Ï is the amount of charge per unit volume (cube), surface charge density Ï is amount per unit surface area (circle) with outward unit normal nÌ, d is the dipole moment between two point charges, the volume density of these is the polarization density P.
