In polytropic process if we know p1,v1,v2 and q(heat added in process) then what will be the value of p2 and the coff. Of expansion (n) ?
i want to ask that sir ,in a polytropic expansion of a gas if we know the initial pressure and initial volume of gas and the heat added in the the gas during expansion and we also know the final volume of the gas , then what will be the final pressure of gas and the coff. of expansion ??Andrew Mason said:Welcome to PF Rakesh!
Unfortunately, this appears to be a thermodynamics problem, not quantum physics. It is also not very clearly explained, which is likely why no one has responded. I would suggest that you post it in the Homework - Introductory Physics board and follow the template for posting a problem. Make sure that you give us the exact wording of the problem that you are trying to solve and show us what you have done to attempt a solution.

A polytropic process with heat addition is a thermodynamic process in which a gas undergoes a change in pressure and volume while heat is added to the system. This type of process is commonly used in engines and compressors.
The equation for a polytropic process with heat addition is PV^n = constant, where P is the pressure, V is the volume, and n is the polytropic index. The polytropic index represents the ratio of specific heats of the gas and is typically between 1 and 1.4 for gases.
The polytropic index in a polytropic process with heat addition represents the efficiency of the process. A higher polytropic index indicates a more efficient process, as it means that less heat is lost to the surrounding environment.
A polytropic process with heat addition differs from other thermodynamic processes in that it allows for heat to be added or removed from the system while the gas undergoes a change in pressure and volume. This makes it a more realistic representation of many real-world processes, such as those used in engines and compressors.
A polytropic process with heat addition has many real-world applications, including internal combustion engines, gas turbines, and air compressors. It is also used in the analysis of refrigeration cycles and other thermodynamic systems.
