A measure of the http://www.answers.com/topic/mechanical-efficiency and economy at which muscles are working when workloads are changed. Delta efficiency is expressed as the percentage ratio of the change in work performed per minute to the change in energy expended per minute
you can use delta in a sentence likewhat is deltahow can delta be useor like delta is important to somethings
delta t is change in temperature
For each delta > 0 there exists some epsilon > 0 such that: |x - y| < epsilon ensures that |f(x) - f(y)| < delta.
Delta is a symbol used in mathematics and science that represents change. For example, delta y over delta x means the change in y over the change in x.

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 formula for calculating the efficiency of a heat engine is: Efficiency 1 - (Tc/Th), where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir.
The assumed efficiency is 100% without any friction
The formula for calculating the efficiency of a heat pump is the ratio of the heat output to the energy input, expressed as a percentage. It can be calculated using the formula: Efficiency (Heat Output / Energy Input) x 100.
There are three methods in calculating the national income. One is the net output method. Another is the income method, and lastly, the outlay method.
The formula for calculating the change in the independent variable, delta x, in a mathematical function or equation is: delta x x2 - x1 Where x2 is the final value of the independent variable and x1 is the initial value of the independent variable.

The formula for calculating the efficiency of a heat engine is Efficiency (Work output / Heat input) x 100. This formula is used to determine how effectively the engine converts heat into useful work. A higher efficiency value indicates that the engine is more effective at converting heat energy into mechanical work, while a lower efficiency value indicates that more heat energy is wasted. By calculating the efficiency of a heat engine, engineers can assess its performance and make improvements to increase its efficiency.
The formula for calculating the length of a chord in a circle is (2rsin(frac2)), where r is the radius of the circle and is the central angle subtended by the chord.
