Pelton Wheel Turbine: Parts, Working, Efficiency, Advantages, Disadvantages, Applications [With PDF]

The Pelton wheel or Pelton wheel turbine is a tangential flow impulse turbine used for high heads of water. The Pelton wheel turbine is invented by Lester Allan Pelton, an American Engineer. The energy available at the inlet of the turbine is only kinetic energy. The pressure energy at the inlet and outlet of the […]

Kaplan Turbine: Parts, Working, Applications, Advantages, Disadvantages [PDF]

Kaplan Turbine is an axial reaction flow turbine and has adjustable blades. If water flows parallel to the axis of the rotation of the shaft, the turbine is known as the axial flow turbine.  And if the head of the inlet of the turbine is the sum of pressure energy and kinetic energy during the flow […]

Hydraulic Turbine: Definition, Types, Working Principle, Disadvantages, PDF

Hydraulic Turbine Definition: Hydraulic Turbine is a device that converts the energy in a stream of fluid into mechanical energy by passing the extreme through a system of fixed and moving blades and causing the wheel to rotate. In simple terms, the Turbine is like Power producing machines. Water turbine was developed in the 19th […]

Rotary Vane Compressor: Definition, Working Principle, Application, [PDF]

Rotary Vane Compressor was invented by Charles C. Barnes of Sackville, New Brunswick, who patented it on 16 June 1874. Rotary Vane Compressor:  This is a positive-displacement pump that consists of vanes mounted to a rotor that rotates inside a cavity. The vane-type compressor consists of a cylindrical rotor with longitudinal slots in which radial sliding vanes are fitted. The rotor is […]

Centrifugal Pump-Parts, Working principle, Application, Disadvantage, PDF

Centrifugal Pump Definition: The hydraulic machine which converts the mechanical energy into Hydraulic energy is called Pumps. The hydraulic energy is in the form of pressure energy, If the mechanical energy is converted into pressure energy by means of a centrifugal force acting on the fluid, the hydraulic machine is called a Centrifugal pump. Centrifugal Pump […]

Siphon: Definition, Working Principle, Uses or Application, PDF

Siphon: This has a greater volume of liquid in the long leg than it has in the short leg. The weight of the liquid in the long leg is acted upon by gravity and when the liquid flows out from the end of the airtight siphon conduit, vacuum suction is created and the siphon draws […]

Limitation of Bernoulli's Equation, PDF

Limitation of Bernoulli's Equation: 1. The velocity of liquid particles in the center of a pipe is maximum and gradually decreases towards the wall of the pipe due to friction. so only the mean velocity of the liquid should be taken into account because the velocity of liquid particles is not uniform. 2. There is […]

Difference Between Impulse and Reaction Turbine [With PDF]

The main differences between Impulse and Reaction turbines are, all hydraulic energy is converted into kinetic energy by a nozzle in the Impulse turbine and whereas In Reaction turbine Only some amount of the available energy is converted into kinetic energy. Before moving to further detailed explanation lets have some overview of Impulse and Reaction […]
