Little problem to project air circulation

[kips0n]

Hello growers! My question is how i can calculate passive intake air
hles at the bottom.

My cab dimensions [m] 0,6 x 0,7 x 1,8
V= 0,756

Here is my fan specification

i want to plug fan on LS
I think i can make only passive holes at bottom but i dont know what diameter should be

Somebody can help me make a very good circulation?

peace!

The diameter of the intake is 100 mm and the usual wisdom is 2x the area of the intake, so :


Radius =50mm
Intake area = 7854 mm^2
2x Intake area = 157 cm^2

more is better. 200 cm^2 is a good place to start.

Sry but i dont understand this..

I should make 2 holes fi50?

Faire un ou plusieurs trous. La superficie totale pour tous les trous doit être de 200 centimètres carrés. Si vous ne aimez pas mes français alors vous devriez remercier Google translate.

Désolé pour mon français.

What language would you like to use?

Powinieneś zrobić jeden lub więcej otworów.Łączna powierzchnia wszystkich otworów powinna wynosić 200 centymetrów kwadratowych.

ok now i understood ;d

but 2m2 is quite a few
thanks for all


and your france lang is good

Nie. Nie myślimy prawidłowo. 200 centymetrów kwadratowych do otworu. 2 metrów kwadratowych jest 20.000 centymetrów kwadratowych.

Masz rację, 2 metrów kwadratowych będzie zbyt duży.

10 cm wysokość x 20 cm szerokość = 200 centymetrów kwadratowych

No. You are not think properly. 200 square centimeters in the hole. 2 square meters is 20000 square centimeters.

You are right, 2 square meters will be too big.

10 cm height x 20 cm width = 200 square centimeters

No. Vous pensez pas correctement. 200 centimètres carrés dans le trou. 2 mètres carrés est 20 000 centimètres carrés.

Vous avez raison, deux mètres carrés seront trop gros.

10 cm largeur x hauteur 20 cm = 200 centimètres carrés

area of a circle = pi x r*2

sooo you think wrong

coz 10x20=200 is good when you make a square not circle
