Course description and aims
By leveraging the basic principles and concepts to understand fluid dynamics that was learned in Hydraulic I, this lecture provides important concept and solutions (equations) to understand flow dynamics in conduit and open channel, which can be can be applied for designing such water infrastructure. On the basis of the laws of conservation of momentum and energy, the first half of this lecture explains fundamental concepts to understand friction and resistance in laminar and turbulent flow, and then the second half introduces the important equations to describe steady flow of conduit, and steady and unsteady flow of open channel.
This lecture aims to deepen the understanding of the basic principles and fundamental phenomenon of water flow, and to understand the dymanic and complex flow dynamics. Such understanding will help students obtain a foundation of design techniques required for flood control, water use, and environmental management.
