What law is best described the statement?
Charles's Law
Boyle's Law
Avogadro's Law
Which of the following statement describes the Charles' Law?
Under the same conditions of temperature and pressure, equal volumes of all perfect gases contain the same number of molecules
For a given weight of gas, at a given temperature, the volume varies inversely as the pressure
For a given weight of gas, at a given pressure, the volume varies directly as the absolute temperature
Select which one is the ideal gas law?
PV=nRT
PT=nRV
A gas cylinder contains propane with a molecular weight of 44.1 lb.mollb at 1000 psia and 70 °F . If the cylinder has a volume of 3 cu-ft, calculate the mass of propane in the cylinder?
8.46 lb
23.26 lb
20.12 lb
32.24 lb
Which of the formula is for the density of perfect gas?
ρ=(MW)PRT
ρ=RT(MW)P
A gas mixture contains 60 wt% of methane. What is the weight of methane if the total gas mixture is 100 lb?
30 lb
40 lb
59 lb
60 lb
A gas mixture contains 77.86 mol % of methane. What is the weight of methane in 1 mol basis if the methane molecular weight is 16 lb.mollb ?
1 lb
2.45 lb
16 lb
12.46 lb
From chart estimate the critical pressure (Pc) and critical temperature (Tc) of gas with a specific gravity of 0.6?
Pc = 675 psia
Tc = 360 °R
Pc = 600 psia
Tc = 300 °R
Pc = 700 psia
Tc = 400 °R
Pc = 550 psia
Tc = 450 °R
If Pc = 675 psia and Tc = 360 °R , determine the pseudo reduced pressure (Ppr) and temperature (Tpr) for gas at 2500 psia and 560 °R
Ppr = 3.00
Tpr = 1.32
Ppr = 3.70
Tpr = 1.56
Ppr = 2.56
Tpr = 1.46
Ppr = 4.20
Tpr = 2.56
If the gases' Ppr = 3.70 and Tpr = 1.56, determine the compressibility factor, z of the gas
z = 0.85
z = 0.8
z = 0.9
z = 0.87
