I got up for awhile today and able to get a little
more info. With engine running and cooling system pressurized I found that with
a single pump running in the series configuration flow was only ~15% reduced
from previous flows without the spare pump. However use of both pumps increased
flow by ~30% over a single pump. In an extended climb I found that temps began
to climb faster than previous, but turning on the second pump reduced the
temps.
Great info. The big
question is still the flow rate with one pump seized. When I get my pumps,
I'll try a simple test with a garden hose so see if I can figure out how much
this might reduce the flow. It won't be nearly as scientific as you tests,
but I don't have an account at the mill store
:-)
Unfortunately
while I was out flying in the blue skies south of the airport, a thunderstorm
moved in over the airport.
Like I said before, your
flight reports are never boring... Sorry to hear about the damage, but it
sure could have been a whole lot
worse.
Cheers,
Rusty
