Overall efficiency is simply the product of volumetric and mechanical/hydraulic efficiency. So continuing with the above example, the overall efficiency of the pump is 0.9 x 0.91 x 100 = 82%. Overall efficiency is used to calculate the drive power required by a pump at a given flow and pressure.

But the efficiency we look at is based on several calculations which can leed to very distracting results. The general rule is still: efficiency between 1.95 and 2.05 (resp. 105%) is okay, everything else is not reliable. @Patty - the r² is a measure of the goodness of fit of your regression line.

This energy efficiency calculator is a simple tool for calculating the ratio of useful energy output to the energy input. You can use it for determining the proportions of heat energy, electric power, mechanical work, or even chemical energy.

The basic formula for an efficiency ratio is expenses divided by revenue. Here’s an efficiency formula example. Say your expenses in a given quarter were $20,000 and your revenue was $60,000. By dividing $20,000 by $60,000, you would get an efficiency ratio of 33 percent.

Efficiency is defined as the ratio of energy output from the solar cell to input energy from the sun. In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell.

Efficiency is the (often measurable) ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result. In a more general sense, it is the ability to do things well, successfully, and without waste.

What is Allocative Efficiency? Home » Accounting Dictionary » What is Allocative Efficiency? Definition: Allocative efficiency is an economic concept that occurs when the output of production is as close as possible to the marginal cost. In this case, the price the consumers are willing to pay is almost equal to the marginal utility they ...

Thanks to the work of a 19th-century engineer named Sadi Carnot, you can apply the law of conservation of energy to measure the heat efficiency of an engine. Given the amount of work a heat engine does and its efficiency, you can calculate how much heat goes in and how much comes out (along with […]

· Efficiency Calculations for Power Converters A power converter’s efficiency (AC-DC or DC-DC) is determined by comparing its input power to its output power. More precisely, the efficiency of the converter is calculated by dividing the output power (Pout) by its input power (Pin). ...

The chiller system is recirculating 40 gallons per minute of water that is chilled by 24 degrees F and using 24.8 kW/hr of electricity to produce the refrigeration. With this information you can calculate chiller efficiency in terms of the energy efficiency ratio, or EER, and the coefficient of …

The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas; 5 - 20% for fuel oil; 15 - 60% for coal

· We have lots of assumptions about how work gets done that don’t mirror exactly what happens. After all, during the day-to-day grind, we don’t think about how we do the work, we often just do it. Ask an outside observer to record the steps of the process in a way that he/she could repeat it themselves if they had to, without assistance.

Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work.There are two classifications of thermal engines- Internal combustion (gasoline, diesel and gas turbine-Brayton cycle engines) and; External combustion engines (steam piston, steam turbine, and the Stirling cycle engine).

Efficiency definition, the state or quality of being efficient, or able to accomplish something with the least waste of time and effort; competency in performance. See more.

Efficiency is a measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage. A perfect process would have an efficiency ...

· Then, if "efficiency" happened to mean what we guessed, you could do the calculation. That formula you mentioned, "multiply the mass and the distance, and then divide that by the length of the arm", gives some mass as the answer. Your answer probably has some units, maybe kilograms. For answers with units, the units are very important.

As a transformer being highly efficient, output and input are having nearly same value, and hence it is impractical to measure the efficiency of transformer by using output / input. A better method to find efficiency of a transformer is using, efficiency = (input - losses) / input = 1 - (losses / input).
