Hydraulic Jump: Formula, Rectangular, Triangular Channel and Table| Fluid Mechanics

Hydraulic Jump: Formula, Rectangular, Triangular Channel and Table! The Hydraulic Jump or Standing Wave: We know that for a given discharge per unit width of a channel, for a given value of the specific energy head E there can be two possible depths of flow d1 and d2. For instance corresponding to specific energy head E = OG [Fig. 14.82], [...]

Measurements of Water Level: Methods, Velocity ,Discharge and Instruments | Fluid Mechanics

Measurements of Water Level: Methods, Velocity ,Discharge and Instruments . In this article we will discuss about the various devices and instruments used in the measurements of water levels, velocity and discharge. Water Level Measurements: The gauges used for water level measurements may be classified into: (i) Non-self-registering gauges, and (ii) Self-registering gauges. The non-self-registering gauges need an observer to [...]

Forces Exerted by Moving Fluid on Immersed Bodies: Drag and Lift and Submerged Objects| Fluid Mechanics

When a body is placed in a moving fluid, a force is exerted on the body by the moving fluid. Similarly when a body moves within a fluid at rest then also a force is exerted on the body by the fluid. Motion of submarines, torpedos and aeroplanes are examples of this kind. Consider a body placed in a fluid [...]

Comparison between Reaction and Impulse Turbines | Fluid Mechanics

Learn about the comparison between reaction and impulse turbines. Comparison # Reaction Turbine: 1. Only a part of the available total head is converted into kinetic head after the water enters the wheel. 2. The velocity and pressure change as the water flows through the wheel. 3. The wheel is always full of water. Water flows into the wheel throughout [...]

Impact of Jet on a Plate or Vane: Notes and Viva Questions| Fluid Mechanics

Impact of Jet on a Plate or Vane: Notes and Viva Questions. Introduction to Jet: A jet of water issuing from a nozzle has a velocity and hence it possesses a kinetic energy. If this jet strikes a plate then it is said to have an impact on the plate. The jet will exert a force on the plate which [...]

Centrifugal Pump : Notes, Application, Methods, Principle and Diagram

Centrifugal Pump : Notes, Application, Methods, Principle and Diagram! Notes on Centrifugal Pump: While a turbine is a device to convert hydraulic energy into mechanical energy, a pump is a device to convert mechanical energy into hydraulic energy. A centrifugal pump acts as a reversed turbine except that in this device special modifications are made to increase the efficiency. Centrifugal [...]
