For air temperatures near 25 degrees Celsius and pressures in the range of 0 to 50 bar, the Joule-Thomson coefficient values are all reasonably clost to 0.2 degrees C/bar. Estimate the final temperature of the gas if 58g of air at 25 degrees Celsius and 50 bar undergoes a Joule-Thomson throttling to a final pressure of 1 bar. Assume the Joule-Thomson coefficient is independent of temperarture and pressure.
