Ernest,

I had no idea that water viscosity changed that much with=20 temperature. Is the same true of 50 - 50 glycol & water?

Tracy

=20 Then:

v =3D pir ^4 p/8cl

*Viscosity of Water as a = Function of=20 Temperature*
Temperature
/=B0C Viscosity
/cP
20 = 1.002
40=20 0.653
60 0.467
80 0.355
100 0.282

Pump A = Only:
14.0=20 V 8.4 A 6 = GPM 56=20 F

56F =3D> 14C
180F =3D> 82C

My = reasoning:
All other=20 factor being equal, cutting the viscosity to 1/3 will triple
the=20 flow. If the WP136 flows 6GPM at 56F, it can be expected to flow =
18GPM at 180F, closer to 20GPM at 190F.

Ernest (also a true = believer, but so were all those people at=20 Jonestown)
