Kinetic Energy - (Measured in Joule) - Kinetic Energy is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its …
WebOct 4, 2012 · 2. There are various definitions of efficiency when it comes to compressors and turbines. Any efficiency is going to a function of what you put in divided by what you "get out". A common definition is something like. Or basically, the ratio of the work we're inputting divided by the enthalpy rise in the stage. WebSo, for compressors, it is the stage efficiency of a multistage compressor containing similar efficiency. Polytropic efficiency is defined as: Where, = polytropic efficiency n = polytropic exponent / number of moles k = isentropic component. Compressors have a polytropic efficiency of 80-85%.
WebThe overall efficiency of a turbocharger is obtained by multiplying the compressor efficiency, mechanical efficiency, and turbine efficiency together to produce a single value of efficiency. The compressor efficiency can be found from the compressor's performance map.
