One of the first engineering problems humankind faced as cities were developed
was the supply of water for domestic use and irrigation of crops. Our
urban lifestyles can be retained only with abundant water, and it is clear
from archeology that every successful civilization of prehistory invested in
the construction and maintenance of water systems. The Roman aqueducts,
some of which are still in use, are the best known examples. However, perhaps
the most impressive engineering from a technical viewpoint was done
at the Hellenistic city of Pergamon in present-day Turkey. There, from 283
to 133 BC, they built a series of pressurized lead and clay pipelines (Fig.
1–11), up to 45 km long that operated at pressures exceeding 1.7 MPa (180
m of head). Unfortunately, the names of almost all these early builders are
lost to history. The earliest recognized contribution to fluid mechanics theory
was made by the Greek mathematician Archimedes (285–212 BC). He
formulated and applied the buoyancy principle in history’s first nondestructive
test to determine the gold content of the crown of King Hiero I. The
Romans built great aqueducts and educated many conquered people on the
benefits of clean water, but overall had a poor understanding of fluids theory.
(Perhaps they shouldn’t have killed Archimedes when they sacked
Syracuse.)
