Sorry for my lack of knowledge but I have searched and searched to no avail. I am in a unique situation. I have to figure out how to cool a 4000kva transformer in a existing coal mine power center. I am going to have a tube above the coils on this transformer with holes cut out above each coil...
I am designing a tunnel boring machine power center. Ive been able to calculate ventilation for natural convection but the customer wants filters. I need to know how to combine the static pressure of the filters with the ventilation open area. Anyone know how this is done?
