density = mass/volume
Gradient= change in field value divided by the distance
Efficiency = Output value / Input valueFor example, if a machine needs 10 KW to run and produces 8 KW, its power efficiency is 8/10 = 0.8 or 80%Efficiency is always between 0 and 1 (or 0 and 100 if expressed as a percentage.)
Area=Length x width or A= L x W
No. It is an estimated equation that defines the best linear relationship between two variables (or their transforms). If the two variables, x and y were the coordinates of a circle, for example, any method for calculating the regression equation would fail hopelessly.
How to calculating cooling efficiency of air cooler
General formula for calculating efficiency is given by Efficiency = (output / input) * 100 It is denoted by greek letter Eta Efficiency cannot be more than 100%.
Efficiency % = (Output/Input) x 100
The assumed efficiency is 100% without any friction
By calculating the discriminant of the equation and if it's negative the equation will have no solutions
There are a great many equations for calculating current; it depends on the context in which you need to calculate current.
V=distance divided by time
density = mass/volume
jedofed
wave speed= frequency/wavelenth
Speed= distance over time. :)
To calculate standard time, subtract the equation of time from the sundial time, then subtract the longitude from the answer you get.
