10.73 An engineer is making an
estimate of hydroelectric power for a
home owner. This owner has a small
stream (Q = 2 cfs, T = 40 °F) that is
located at an elevation H = 34 ft above
the owner's residence. The owner is
proposing to divert the stream and
operate a water turbine connected to
an electric generator to supply
electrical power to the residence. The
maximum acceptable head loss in the
penstock (a penstock is a conduit that
supplies a turbine) is 3 ft. The
penstock has a length of 87 ft. If the
penstock is going to be fabricated
from commercial-grade, plastic pipe,
find the minimum diameter that can
be used. Neglect component head
losses. Assume that pipes are
available in even sizes-that is, 2 in., 4
in., 6 in., and so on.
