How To Design My Whirlpool Inlet For My Whirlpool Tun?

In general, brewing includes mashing, lautering, boiling, whirlpool and wort cooling.

After boiling, the hopped wort settles to clarify in a vessel called a "whirlpool tun", 

where the more solid particles in the wort are separated out.

A whirlpool should have no internal protrusions that might slow down the rotation of the liquid. 

And the bottom of the whirlpool is often slightly sloped towards the outlet.

Smaller breweries often use the brew kettle / boiling kettle as a whirlpool tun. 

While in most large breweries, there is a separate tank for whirlpool. 

These tanks have a large diameter to encourage settling, 

and is flat bottomed or with a slope of 1 or 2° towards the outlet, a tangential inlet near the bottom of the whirlpool, 

and an outlet on the bottom near the outer edge of the whirlpool.

To get a good whirlpool project, a right direction design of tangential inlet is also very important.

Is clockwise or anticlockwise direction better? Well, it depends on your location. 

Your area decides the earth rotates. Let me make it simple, the whirlpool inlet should be same as the earth rotates. 

That is to say anticlockwise is a good choice if you are located in the Northern Hemisphere. 

on the contrary, if you are in Southern Hemisphere, the rotation direction should be clockwise to get better whirlpool effect.
