Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal n̂, d is the dipole moment between two point charges, the volume density of these is the polarization density P.
The CLF is the cooling load at a given time compared to the heat gain from earlier in the day. [1] [5] The SC, or shading coefficient, is used widely in the evaluation of heat gain through glass and windows. [1] [5] Finally, the SCL, or solar cooling load factor, accounts for the variables associated with solar heat load.
In electrical engineering the load factor is defined as the average load divided by the peak load in a specified time period. [1] It is a measure of the utilization rate, or efficiency of electrical energy usage; a high load factor indicates that load is using the electric system more efficiently, whereas consumers or generators that underutilize the electric distribution will have a low load ...
The LLF value naturally depends on the load profile. For electricity utilities , numbers about 0.2-0.3 are typical (cf. 0.22 for Toronto Hydro , [ 3 ] 0.33 for New Zealand [ 4 ] ). Multiple empirical formulae exist that relate the loss factor to the load factor (Dickert et al. in 2009 listed nine [ 5 ] ).
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
A series of mixed vertical oscillators A plot of the peak acceleration for the mixed vertical oscillators. A response spectrum is a plot of the peak or steady-state response (displacement, velocity or acceleration) of a series of oscillators of varying natural frequency, that are forced into motion by the same base vibration or shock.
Tables of Physical and Chemical Constants and Some Mathematical Functions is a scientific reference work. First compiled and published in 1911 by the physicists G. W. C. Kaye and T. H. Laby , it is more commonly known as Kaye and Laby . [ 1 ]
In physics, Peek's law defines the electric potential gap necessary for triggering a corona discharge between two wires: = e v is the "visual critical corona voltage" or "corona inception voltage" (CIV), the voltage required to initiate a visible corona discharge between the wires.
