Engineering of Water Systems

摘要

In last month's installment of The Water Works we began a discussion of fluids in motion, or hydrodynamics, as it relates to the engineering and design of groundwater sys-tems by introducing the physical laws associated with this science. We continue this month by providing two equations com-monly used to calculate the specific friction loss of a closed or open conduit or flow path, along with a group of pre-prepared head loss charts and correction factors for various types and pressure classes of pipe. All will assist a designer with deter-mining the friction loss of their own individual system design.
