Nitrogen gas at a pressure of 100 Bar and -70oC is contained in a tank of 0.25 m3. Heat is added until the temperature is 37oC. Determine approximately, through the use of Z factor, (a) Specific volume of gas, in m3/kmol (b) The final pressure, in Bar. Data for N2: Pc = 33.9 Bar Tc = 126.2 K
Nitrogen gas at a pressure of 100 Bar and -70oC is contained in a tank of 0.25 m3. Heat is added until the temperature is 37oC.
Determine approximately, through the use of Z factor,
(a) Specific volume of gas, in m3/kmol
(b) The final pressure, in Bar.
Data for N2: Pc = 33.9 Bar Tc = 126.2 K
The compressibility factor, often represented as
It relates the molar volume of a gas to the molar volume of an ideal gas under the same conditions.
Using the Z factor in conjunction with the ideal gas law can help us determine various properties of a gas.
For non-ideal gases, pressure calculations often require an iterative process, as the compressibility factor may change with pressure.
