It is an overflow structure built across an open channel for the purpose of measuring and controlling the flow.
It is a pressure force that acts as the body submerged in a liquid at rest which is equal to the weight of the fluid displaced by the submerged body either partially or completely.
A principle in flow measurement which states that the increase in kinetic energy per unit weight is equal to the decrease in the potential energy per unit weight is known as:
The Venturi meter is used to measure the presence of flow in the pipe system, the section of the pipe with the smallest pressure is called:
A mechanical device which when installed in the pipe flow system will add energy (output) to the system is known as:
In fluid flow, if the fluid travels parallel to the adjacent layers and the paths of individual particles do not cross, the flow is said to be:
Problem
A triangular shaped channel is to be designed to carry 700 L/s on a slope of 0.0001. Determine what vertex angle and depth of water over the vertex will be necessary to give a section with minimum perimeter, assuming the channel is made of timber, n = 0.012. Use Manning’s formula.
