Error Analysis for Electromagnetic Surface Velocity and Discharge Measurement in Rapid Mountain Stream Flow

→ Bernoulli equation can be applied to any streamline.. The concepts of the stream function and the velocity potential can be used for developing of differential

For irrotational flow of ideal incompressible fluid, the Bernoulli’s equation applies over the whole flow field with a single energy line. Exact velocity field

- Prove or give a counter-example of the following statement: In three space dimensions and time, given an initial velocity field, there exists a vector velocity and

1) drag force = component of the resultant force in the direction of relative velocity V 0 2) lift force = component of the resultant force normal to the relative velocity V

• Inertial sub-layer, viscosity plays a minor role. • Main turbulent

- Relate the mixing length to velocity gradient using the similarity rule - Turbulent fluctuations are similar at all point of the field of flow. - Velocity is characteristics

Assumptions: neglect velocity head and minor losses Given: pipe length, pipe diameter, f, water surface level Find:

For laminar flow, head loss varies with the first power of the velocity.(Fig.. Equating the Darcy-Weisbach equation for head
