Air-leakage-loss by
Although the
valve in the cover
should not be airtight,
the power
lost will only be
in proportion to so
much air as can
rush in in the chamber
before the water
has risen its
utmost.
Besides the force
of gained by the
fall of water
something might
be done by means
of the blast of Air.
See Lewis's Concise
Philos.
The moment
the pressure
within ceases to
be greater than the
pressure without,
that is, the moment
that air ceases to
be driven out the
weight of valve
will make it full
it shut it. That
same moment
the force of the
air in the pond
will force up the
water, & raise the
valve.
