Question

Explain what is meant by the term "partial pressure" in your own words.

A pressure vessel containing 20kg of butane (C4H10) and 25kg of propane (C3H8) is at a pressure of 50 bar at 124 degrees Celsius. Calculate the volume of the pressure vessel using Kay's Rule. (Answers: 0.181 m³)

Calculate the volume of air (at atmospheric pressure, 25 degrees Celsius) that will be required to mix with the contents of the pressure vessel to ensure complete combustion. (Answers: 619 m³)

	Propane	Butane
Molar Mass kg/kmol	44	58
Critical Temperature oC	96.8	152
Critical Pressure, bar	42	37.5

Answer 1

actual procedure is mentioned . but I am not getting the above answers mentioned may be the compressibility factor choosed is wrong
