What is the relationship between water curtain and ventilation in pigsty?

First, according to the size of your pigsty and the number of pigs, calculate the air demand, that is, ventilation. Generally, the smallest is given, and dividing by 0.4 is the largest.

Then divide the maximum ventilation volume by 1.5 (normal primary wind speed) to get the water curtain area. Because all air inlets are in the water curtain, the water curtain area * wind speed = all ventilation.

If you don't know, you can find a professional to look at the site, make a reasonable ventilation and cooling plan according to the actual situation, and then determine the number of fan water curtains.
