Heat Gain Thru HEPA FIlters

Heat Gain Thru HEPA FIlters

Heat Gain Thru HEPA FIlters

(OP)
I'm looking for an equation to determine the heat gain (delta T) of an air stream passing through a HEPA filter.  I have the flow rate, velocity, static press. loss, and I'm sure there's a way to determine the heat gain to the air from the pressure loss, I just can't seem to locate it.

I believe I once saw in ASHRAE a section that discussed the conversion of static pressure to heat (not just for HEPA's but for any friction source).

thanks in advance

RE: Heat Gain Thru HEPA FIlters

I'll have to work in SI units here, as I'm most familiar with them...

Power (W) = Flow (m3/s) x Total Pressure Drop (N/m2)

Just about all of this becomes heat.

Regards,

Brian

RE: Heat Gain Thru HEPA FIlters

If the motor is in the air stream, it would be the extra HP required to overcome the static resistance of the filter.
