=A0
so, we know that:=A0=A0=A0 =A0little=20 flow (gals/rev) X cranking speed(rpm) X (3-5 secs) / 60 =3D good sized pudd= le=20 (gal)
=A0
which also can be produced by:=A0=A0=20 =A0the average 10 week old puppy(wks) in an eyeblink(millisecs) 3-5 seconds= =20 after drinking water(gal) and forgotten instantaneously(over zero).=A0=A0= =20 now, to solve for "little flow" we first divide by both equations= by 3-5=20 seconds, then.......
=A0
I'm so glad we have engineers to do a= ll the math=20 for us!=A0=A0=A0=A0 :-)=A0=A0 kevin
