head loss उदाहरण वाक्य

The rate of energy dissipation or head loss across a hydraulic jump is a function of the hydraulic jump inflow Froude number and the height of the jump.
There is not much head loss between cross section 1, before the contraction, and cross section 3, the vena contracta at which the main flow is contracted most.
An emitter restricts water flow passage through it, thus creating head loss required ( to the extent of atmospheric pressure ) in order to emit water in the form of droplets.
During this period he modified the Prony equation for calculating head loss due to friction, which after further modification by Julius Weisbach would become the well-known Darcy Weisbach equation still in use today.
It is achieved by reducing turbulence and friction in the fluid flow ( that is, minimizing head loss ), and by providing a way to remove any inoperative pumps from the fluid path.

Trash racks are designed for water velocity of around 2 feet / second ( 0.6 metres / second ) to prevent excessive energy loss due to the head loss across the trash rack.
About 650, 000 cattle are sold to slaughter every week in the U . S . At a $ 100 a head loss, the nation's cattle growers are collectively losing $ 65 million a week.
When a system includes a centrifugal pump, an important design issue is matching the " head loss-flow characteristic " with the pump so that it operates at or close to the point of its maximum efficiency.
:A curve used to display the amount of back pressure ( head loss, feet ) that a given circulating pump would be able to overcome at a given flow rate, typically provided by the pump manufacturer.
Once the friction factors of the pipes are obtained ( or calculated from pipe friction laws such as the Darcy-Weisbach equation ), we can consider how to calculate the flow rates and head losses on the network.
