A perfect process would have an efficiency of 100.

Energy efficiency calculator physics.

Instead of focusing on the energy efficiency of a single item such as an appliance we can also look at the energy efficiency of whole buildings. If two buildings are supplied with the same amount of energy to create heat the building that can generate and retain the most heat. Energy cannot be created or destroyed only converted from one form to another. W in the work or energy put in to a process.

Ke 1 2 mv 2. A good result for that might be for example 4 3 that would mean that paying for 1 joule of electrical energy is enough to pump 4 3 joules of heat out of your house. This energy efficiency calculator is a simple tool for calculating the ratio of useful energy output to the energy input. The above explanation is for the use of efficiency in physics and thermodynamics but efficiency can be used in anything from finance to work performance.

Units are joules j. These conversions can be shown in sankey diagrams. η efficiency greek letter eta w out the work or energy produced by a process. Physics is really nothing more than a search for ultimate simplicity but so far all we have is a kind of elegant messiness physics is indeed the most fundamental of the sciences that tries to describe the whole nature with thousands of mathematical formulas.

Work and energy both use the standard unit of joules but the calculator above is unit less to allow you to input any unit. Free online physics calculators mechanics energy calculators. Efficiency is a measure of how much useful energy is converted. Energy efficiency measures the proportion of energy which is wasted.

Units are joules j. The term energy efficiency can also be used in a wider sense. For example the efficiency of an air conditioner is often taken to mean the ratio of the energy it pumps out of a room to the energy it draws from the electrical outlet. The efficiency is the energy output divided by the energy input and expressed as a percentage.

Having an efficiency of 80 percent means that only 80 of the energy provided by the source is converted into work done by the machine. Calculate the unknown variable in the equation for kinetic energy where kinetic energy is equal to one half times the mass multiplied by velocity squared. The rate at which energy is wasted needs to be reduced and there are a number of ways to save energy especially thermal energy. The rest 20 has turned into other forms of energy such as heat light sound energy etc.
