The Hartmann number calculator computes the ratio of electromagnetic force to the viscous force.
INSTRUCTIONS: Choose units and enter the following:
Hartmann number (Ha): The calculator returns the ratio as a real number.
The Hartmann Number equation is used to computes the ratio of electromagnetic force to the viscous force. The Hartmann Number equation is as follows:
`Ha=B*Lsqrt(sigma/mu)`,
where:
This ratio was developed by Julius Hartmann of Denmark.
