What is the use of paddle wheel?

What is the use of paddle wheel?

The paddle wheel is a device for converting between rotary motion of a shaft and linear motion of a fluid. In the linear-to-rotary direction, it is placed in a fluid stream to convert the linear motion of the fluid into rotation of the wheel.

What is usually the motor speed of paddle?

In the tank several paddles may be mounted one above the other on the same shaft. Industrial paddle agitator turn at speeds between 20 and 150 rpm. The total length of the paddle impeller is typically 60% to 80% of the inside diameter of the vessel.

Why Pelton wheel is used for high heads?

The formula implies that the Pelton turbine is geared most suitably for applications with relatively high hydraulic head H, due to the 5/4 exponent being greater than unity, and given the characteristically low specific speed of the Pelton.

Which device is responsible for converting pressure energy to kinetic energy in Pelton wheel turbine?

Explanation: Impulse Turbine is the one in which pressure energy of water is first converted into kinetic energy by means of nozzle kept close to the runner. Explanation: The pressure of water is atmospheric and remains constant while passing over the runner in Impulse Turbine.

What are the two types of paddle wheels?

Paddlewheels are a historic part of the evolution of boats and water transportation, and were vital in the development of trade and tourism on the Mississippi River. There are two types of paddelwheel steamers: the sternwheeler with a single paddle wheel on the rear, and sidewheelers that have a wheel on each side.

How does a paddle wheel flow meter work?

The paddlewheel sensor is designed to be inserted into the pipe fitting. Approximately one half of the paddle protrudes into the flow stream. Fluid flowing through the pipe causes the paddlewheel to spin.

What is mechanical Flocculator?

MECHANICAL FLOCCULATORS ARE USED IN COAGULATION AND FLOCULATION PROCESSES WHERE SOLIDS ARE SMALL (COLLOIDAL) AND CAN BE RELATIVELY DISPURSED. SPS MANUFACTURES SEVERAL COMMON TYPES OF MECHANICAL MIXERS FOR USE IN FLOCCULATION.

What is flocculation tank?

The flocculation tank has wooden paddle-type mixers that slowly rotate on a horizontal motor-driven shaft. After flocculation the water flows into the sedimentation tanks. Some small water-treatment plants combine coagulation and sedimentation in a single prefabricated steel unit called a solids-contact tank.

What is the efficiency of Pelton turbine?

Pelton turbines can reach up to 95% efficiency, and even on ‘micro’ scale systems 90% peak efficiency is achievable. Also the efficiency is maintained at a high level even for part-flow rates, mainly because of the low-loss design of the spear-jet.

What is mechanical efficiency in case of Pelton wheel?

The efficiency of any mechanical device is defined as the ratio of power output to energy input. The overall efficiency of a turbine is the measure of the performance of the turbine. The overall efficiency of Pelton wheel is approximately 0.85.

What is the maximum efficiency of Pelton wheel?

How is Pelton wheel efficiency calculated?

Hydraulic Efficiency: It is the ratio of power produced by the runner of the turbine to the water-energy supplied to the bucket of the runner. { h }_{ f }=\frac { fL{ V }^{ 2 } }{ 2gD }.

What is the purpose of a paddle wheel?

A paddle wheel is a form of waterwheel or impeller in which a number of paddles are set around the periphery of the wheel. It has several uses, some of which are: Very low-lift water pumping, such as flooding paddy fields at no more than about 0.5 m (20 in) height above the water source for aquaculture.

What is the size of a paddle wheel mixed pond?

Niels-Henrik Norsker, in Handbook of Microalgae-Based Processes and Products, 2020 The largest commercial paddle wheel-mixed raceway ponds are from 0.5 to 1 ha in area and used for cultivation of Spirulina ( Borowitzka, 2005 ). The pond area is limited by the maximum acceptable depth and minimum acceptable flow velocity.
