Adiabatic coefficient of gases - Flammersfeld oscillator
P2320500
Sample resultsfor the adiabatic coefficients. Experimental conditions: Ten measurements, each of about n = 300 oscillations.
Principle
Gas oscillator, Flammersfeld
A mass oscillates on a volume of gas in a precision glass tube. The oscillationis maintained by leading escaping gas back into the system. The adiabatic coefficient of various gases is determined from the periodic time of the oscillation. Tasks 1. Determine the adiabatic coefficient of air nitrogen and carbon dioxide (and also of argon, if available) from the periodic time of the oscillation T of the mass m on the volume V of gas.
