HazenWilliamst
Hazen Williamst was an American civil engineer known for his significant contributions to hydraulics and the development of empirical formulas for predicting water flow in pipes. Born in 1847, Williamst spent much of his career working for municipal water departments, most notably in St. Louis, Missouri. His practical experience led him to investigate the factors affecting the resistance of water flow in pipes, which were often underestimated by existing theoretical models.
Williamst's most famous contribution is the Hazen-Williams equation, an empirical formula that estimates the velocity of
His work on water quality and the treatment of water for public consumption was also notable. Williamst
