Definition of water hammer pressure Water hammer pressure is defined as: The sudden increase in pressure in the pipe lines due to reduction in velocity in a very short time is known as water hammer pressure.
Critical flow The flow at depth equal to the critical depth is known as critical flow.
Types of similarities between model and prototype There are three types of similarities between model and prototype in hydraulic similitude:
True model The models which are prepared with the same scale ratio in different directions are known as Geometrically true models.
Definition of hydraulic similitude Hydraulic similitude is an indication of a relationship between a model and a prototype. Prototype in case of hydraulic similitude is hydraulic structure.
Specific energy Specific energy at a particular section is defined as The total head with respect to the bed of the channel. Or
