What means work output divided by work input?
input force x input distance > output force x output distance -Novanet
In what machine does work input equals work output?
In practical there is no machine which have efficiency 100%,i.e. output work = input work. But an ideal machine have efficiency of 100%, for an example a Carnot's heat engine. The efficiency of this engine is 100% but it is an ideal situation. As an expression of efficiency it is equal to W/Q, where W is work done by the system and Q is heat put into the system. For efficiency =1 ,i.e.100% if and only if W=Q and vice verse.
What is the efficiency of a street cleaner's engine when the heat input is 200000 joules and the heat waste is 150000 joules?
25 percent
What compares the energy output of a system with its energy input?
Is it's Energy Efficiency.
What is the formula of efficiency?
The formula of efficiency is power output divided by the power input.
What is the efficiency of a cars engine when heat input is 2000000 joules and the waste heat is 1500000 joules?
25%Take Input - Waste = Differencethen D / I = Effeciencyso, 400000 - 300000 = 100000and 100000 / 400000 = .25 or 25%now ask the teacher next time...Dont answer the question if you are going to get an attitude...
How do you calculate the efficiency of a machine?
Efficiency is nothing but calculating how the machine is performing for what it has been made for, Efficiency is usually calculated in % as (output/input )X100. for Eg. the Thermal efficiency of an reciprocating gasoline engine can be calculated as follows, Let, the input for an reciprocating engine is 12MJ and its out put is 4MJ then Efficiency is (4/12)X100 = 33%
What is definition of thermal efficiency of gas engine?
In general, efficiency is the ratio between the output of a device and the input, . For thermal efficiency, the input, , to the device is heat, or the heat-content of a fuel that is consumed. The desired output is mechanical work, , or heat, , or possibly both.From the first law of thermodynamics, the energy output can't exceed the input, so
If the boats engine has a heat input of 40000 J with 30000 J exhausted into the surroundings the heat sink what is its efficiency?
efficiency = output/input therefore, in above case it is 3/4= 0.75 or 75%.
What means work output divided by work input?
input force x input distance > output force x output distance -Novanet

Which math ratio represents efficiency?
Efficiency = Output/Input.
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
