Gas Velocity Calculator:>
Enter the values of Gas Constant R(J/K-mol) , Temperature T(kelvin) & Molar Mass M(kg/mol) to determine the value of Gas Velocity Vgas(m/s).
Gas Velocity Formula:
The Gas Velocity Vgas(m/s) in meter per second is equal to the SQRT of the value of 3 into multiply the Gas Constant R(J/K-mol) = 8.3145 J/K-mol in joule per kelvin mol and multiply the Temperature T(kelvin) in Kelvin is divided by the Molar Mass M(kg/mol) in kilogram per mol.
The Formula of Gas Velocity can be writtern as,
Vgas(m/s) = SQRT ( 3 * R(J/K-mol) * T(kelvin) / M(kg/mol) )
Here,
Vgas(m/s) = Gas Velocity in meter per second
R(J/K-mol) = Gas Constant in joule per kelvin mol
T(kelvin) = Temperature in Kelvin
M(kg/mol) = in kilogram per mol
Calculation for Gas Velocity:
1)Determine the Gas Velocity and given for Gas Constant = 8.3145 J/K-mol , Temperature = 300k , Molar Mass = .042 kg/mol.
Answer
Vgas = SQRT ( 3 * R * T / M )
Vgas = SQRT ( 3 * 8.3145 * 300 / .042 )
Vgas = 422.09m/s.
2)Determine the Temperature and given for Gas Constant = 8.3145 J/K-mol , Gas Velocity = 422.09m/s , Molar Mass = .042 kg/mol.
Answer
Vgas = SQRT ( 3 * R * T / M )
422.09 = SQRT ( 3 * 8.3145 * T / .042 )
T = 300k.
