equation that I use :
if k = < 1 and n = < 0 ...............
The equation becomes
Y = k * X^n![]()
that is the formula used by Excel
The same formula used by Martin........for the radiators
Delta temp. vs RPM (Air rate)
"...........The first curve, to me , describe correctly the physical phenomenon.........
follows the points and approaching asymptotically the X axis.
Is very precise for flow rate 100/800 lph........... and also > 800 lph.
Likely for flow rate < 50? lph is less accurate (wrong).
............. "
See above
