There is an ERROR in the DENSITY VALUE given in the video. Please use the density values given in the table below instead!

The density to use for three different cases:

How to Find the Density from the Stokes number?

As we have discussed in the Pre-analysis and Setup section, the Stokes number is the ratio of particle response time to the flow characteristic time scale. Here, in the case of low Reynolds number flow, particle response time is calculated using this formula:

Here, we will use the inverse of the instability growth rate as the flow characteristic time scale:
