The type of energy you want to transfer is known as the input or source of energy, which is typically converted into a different form of energy for the desired purpose. For example, electrical energy may be input to a motor to produce mechanical energy.
Someone pushing against a lever.
Whenever we do any work some energy will be converted into any form other than the actual input energy for the work to be done so it is impossible to have the output greater than work input example : some energy will be converted to heat energy due to friction
The ratio of output to input of energy or power is known as efficiency. It is typically expressed as a percentage, calculated by dividing the useful output energy or power by the total input energy or power and multiplying by 100. For example, if a machine consumes 100 units of energy and produces 80 units of useful energy, its efficiency would be 80%. High efficiency indicates that a system converts a greater proportion of input energy into useful output.
The total energy input can be calculated using the formula: Energy input = Useful energy output / Efficiency Substitute the given values into the formula: Energy input = 20 / 0.25 Energy input = 80 units.
Energy release is to condensation as energy input is to vaporization. Vaporization requires energy input to happen, while condensation releases energy.
An example of an energy balance equation for a steam turbine can be expressed as: Input energy (steam flow rate x enthalpy of steam) Output energy (mechanical work done by the turbine heat losses)
Yes, all ovens/cookers require some energy (fuel) input in order to get them to heat up. For example electric hobs require an electrical imput, gas cookers require gas as their fuel (energy) etc... Even solar cookers have a solar energy input.
Efficiency compares the useful energy output of a system to the total energy input. It provides a measure of how well a system converts input energy into useful output energy.
The ratio of energy output to energy input is the efficiency of a system, and is typically less than 100% due to energy losses. Work input is the amount of energy needed to perform a specific task or operation, and it is dependent on the efficiency of the system.
