WebFeb 23, 2024 · Explanation: Consider a single-stage reciprocating air compressor: We know that the area under the P-V graph gives us the work done. In the graph, we can clearly see that adiabatic compression requires more work than the isothermal process and the remaining two processes given in the options will have their curve above isothermal … WebEnergy storage systems are increasingly gaining importance with regard to their role in achieving load levelling, especially for matching intermittent sources of renewable energy with customer demand, as well as for storing excess nuclear or thermal power during the daily cycle. Compressed air energy storage (CAES), with its high reliability, economic … god is with us hanna varghese

3.6 Adiabatic Processes for an Ideal Gas - OpenStax

Web1 day ago · For a closed system, the first law is written as −. Σ Q = Σ W. But this is only valid for a closed system which is undergoing a cycle. For a process it can be written as −. Q 1 − 2 = U + W 1 − 2. Before we can start modelling these one should know how to model work and heat for different processes. So let us do that first. WebThe polytropic index is that defined via a polytropic equation of state of the form P1+1/n, where P is pressure, is density, and n is the polytropic index. There is a relationship … WebOct 12, 2024 · The polytropic index of space plasmas is typically determined from the relationship between the measured plasma density and temperature.
