Question

What would be the optimal diameter of gold grains if you want to fill a pool with them and swim in it?

Answer 1

Hey mate ^_^

Drag coefficient depends rather weakly on Reynolds number and hence on viscosity...


So even if viscosity decreased several times (if the density remained unchanged) the drag coefficient change would be much smaller so the dynamic of swimming probably wouldn't change much....

Hello mate here is your answer.

The warmer the weather, the faster that swimming bug hits all of us. In my opinion, THE SOONER THE BETTER! So when the sun starts peeking through those rain clouds maybe it’s time to open your pool. You might just need your pool topped off with water. When the weather is consistently around 70 degrees during the day, it may be time to open the pool. Leaving your winter cover on during those hotter days lets day light through the cover. Exposing the water to the sunlight will cause algae to start to form under the winter cover. When this happens all you are doing is getting behind. It is hard to catch up the hotter it gets. THE SOONER THE BETTER. Pollen can also be a pain. The best thing to do is get the winter cover off of the pool as soon as you can, and start to circulate the water. This will let your swimming pool pump and filter system do their job to make your job as a happy swimming pool owner easier.

Hope it helps you.
