No control. Just for additional operational flexibility.

BHP is constant since P = IV and both voltage and current are constant in my case. I guess that means that my increase in delta static pressure across the fan is exactly proportional to my decrease in air flow no...
I have a VFD fan that pushes air through a filter. Over time, downstream resistance gets higher due to the filter. Fan speed remains constant. We have looked at amperage draw and it has remained stable even with this added resistance. Does that mean that air flow remains constant?
Kind of...
I am trying to find the flow rate in a duct that is quite large (around 4'x3') but is very short. This duct leads to a fan which leads to a separate unit through another short duct section. Both these duct sections have different sizes (the fan outlet is much bigger than its inlet). I will take...
integral (x^2 - 2x) e^-x dx
Im just wondering if there's a fast way to calculate this integral or is the only way to do it by parts twice. The prof didnt show any work in the solution and went right to the solution. Am I missing something obvious?
