- nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as … there is some loss of energy is always involved in different ways. Answer   In order for a machine to be 100% efficient, the amount of energy going into it has to be precisely equal to the energy the machine is putting out-with nothing lost.

- At wind speeds above and below the design speed the efficiency is the same or less-maybe much less. If a turbine's best efficiency is 40% at a wind velocity of 9 meters per second (about 20 mph), it will be 40% only at that wind speed. At all other wind speeds it will be something worse.

How Do You Calculate Percent Efficiency? Percent efficiency is calculated by determining the actual output and then dividing by the maximum possible output. The result is multiplied by 100 in order to move the decimal two places to the right. Continue Reading.

- Mechanical advantage is a measure of how much a simple machine multiplies the input force. In this lesson, we learned how mechanical advantage is calculated for two simple machines: levers and pulleys.

Energy efficiency in transport A motorized bicycle such as the Velosolex allows human power and the assistance of a 49 cm 3 (3.0 cu in) engine, giving a range of 160 to 200 mpg-US (1.5–1.2 L/100 km; 190–240 mpg-imp). Electric pedal-assisted bikes run on as little as 1.0 kW·h (3.6 MJ) per 100 km, while maintaining speeds in excess of 30 km/h (19 mph).rom 1960 to 2010 the efficiency of air freight has increased 75%, mostly due to more efficient jet engines. 1 US gal (3.785 l, 0.833 imp gal) of fuel can move a ton of cargo 857 kilometres (533 mi) by barge, or 337 km (209 mi) by rail, or 98 km (61 mi) by truck.

Furnaces and Boilers The AFUE rating for an all-electric furnace or boiler is between 95% and 100%. The lower values are for units installed outdoors because they have greater jacket heat loss. However, despite their high efficiency, the higher cost of electricity in most parts of the country makes all-electric furnaces or boilers an uneconomic choice.

Thermal efficiency When expressed as a percentage, the thermal efficiency must be between 0% and 100%. Efficiency is typically less than 100% because there are inefficiencies such as friction and heat loss that convert the energy into alternative forms.

What Is the Forumla for Efficiency? The formula for efficiency is: efficiency = (useful energy transferred / energy supplied) x 100. It is important to note that the efficiency of any machine or device will always be less than 100 percent. Continue Reading.

What is 'part load efficiency' in the automotive engines? It is maximum at one point which is the design condition and load applied in that case is called as full load i.e. 100% load. Thus, Full load efficiency : Efficiency at the 100% load. Part load efficiency : Efficiency at some specified load value below 100%.

What-Are-Fuel-Efficiency-Ratings As a guideline, a fireplace with a 70-80% efficiency rating would be a dependable choice. Stoves are another great hearth option if you’re not in the market for a fireplace. Able to burn wood, pellets or coal, Harman stoves are built to last and provide unparalleled heat and efficiency.

- Consumers should seek high recovery efficiency ratings from the independent Home Ventilating Institute (HVI). High-efficiency HRVs and ERVs should have HVI-rated of at least 76%. This level of efficiency is required to achieve an ENERGY STAR rating for homes with electric heat. The type of controls offered and the unit's energy efficiency compared to other models should also be considered when choosing a recovery ventilator.

- When a machine turns a small input force into a larger output force, we say that the machine gives us a mechanical advantage. Mechanical advantage (MA) is the ratio of the output force to the input force (for example, the output force divided by the input force).Imagine a hammer pulling a nail out of a piece of wood.

Power The power rating indicates the rate at which that machine can do work upon other objects. Thus, the power of a machine is the work/time ratio for that particular machine. A car engine is an example of a machine that is given a power rating. The power rating relates to how rapidly the car can accelerate the car. Suppose that a 40-horsepower engine could accelerate the car from 0 mi/hr to 60 mi/hr in 16 seconds. If this were the case, then a car with four times the horsepower could do the same amount of work in one-fourth the time.

What's Your Production Efficiency? We'll call the latter factor Mold Efficiency, which tells us how well the molding process ran. Machine Efficiency is simple calculation. It is the machine's run time versus available time. So, a machine that was down two hours of an eight-hour shift has a 75% Machine Efficiency. Because Machine Efficiency is easy to calculate and understand, many molders already track it as a critical performance measure. Mold Efficiency is more abstract.

- 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 of 100%.

The Difference Between Car Engines (Credit: Drivingtestsuccess.com) The efficiency of the piston engine, in general, is around 28 to 45%. It can have hundreds of moving parts that can be the source of more maintenance, noise, and energy losses than in rotary or electric engines, which have fewer parts and less complexity.

- Our problemnow is to keep our efficiency numbers up so we don't have to fire any more workers.e. We're into Quality now. Our goal is to produce quality products, whatever the cost. Our finalinspection is so good that we test for every possible defect. We throw away or rework 30% of theunits we produce.e used to use human inspectors, but the cost of the machine per unit of productinspected is much lower than the cost of human inspectors. The per unit cost of the parts increase ifwe use human inspectors.c. Our problem is not bottlenecks. We don't have any.
