civil engineering summary

Cost-effective duct design is as much an art as it is a science. • Bernoulli’s Law is used to explain the relationship between velocity and static pressures. • Use of straight-forward layouts with efficient fittings is critical in duct design. • Friction loss charts and duct calculators are important tools in reinforcing duct design principles and improving the duct design process.
