cost efficiency is how good what you paid for was for the price you paid for it. it pretty much rates the quality and the price as a comparison in one.
Efficiency effectiveness can only be measured by results; cost efficiency, time efficiency, output efficiency, etc.
say energy costs 5 cents and the efficiency is 0.1kwh cost= 0.1kwh x 0.05 cost= o.oo5cents
Efficiency is: 100% x (the energy that goes to the intended task)/(total energy needed)
the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.
what is the definition of historical cost
The ratio of output to input of a system or process.
geothermal cost money like cost efficiency, it is an expensive price of geothermal, and it has a very big price to pay
radiation use efficiency is the percentage part of incident solar radiation spectrum being utilized by plants.
ampere hour unit of battery
Output work divided by input work
Definition of 'Return On Investment - ROI'A performance measure used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments. To calculate ROI, the benefit (return) of an investment is divided by the cost of the investment; the result is expressed as a percentage or a ratio. The return on investment formula:
You use the definition of "efficiency": you divide output power by input power. Both of these, of course, need to be measured or calculated.
