What is the use of tail race?
The tail race, containing tail water, is a channel that carries water away from a hydroelectric plant or water wheel. The water in this channel has already been used to rotate turbine blades or the water wheel itself. This water has served its purpose, and leaves the power generation unit or water wheel area.
What is tail race and head race?
The race leading to the water wheel on a wide stream or mill pond is called the head race (or headrace), and the race leading away from the wheel is called the tail race (or tailrace).
What is head race in turbine?
head·race. (hĕd′rās′) A watercourse that feeds water into a mill, water wheel, or turbine.
What is the tailrace in a hydro system?
Tailrace: The channel that carries water away from a dam.
What does tail race mean?
: a race for conveying water away from a point of industrial application (such as a waterwheel or turbine) after use.
Which is high head turbine?
High Head. Head differences of 100 meters or higher are considered high head. In this type of plant, water travelling through the turbine comes from a significantly higher elevation, meaning that the system needs a smaller volume of water to produce an equivalent amount of energy.
What is the Tail Race Canal?
The Tailrace Canal is man-made canal and was constructed as part of Santee Cooper’s hydroelectric dam. It’s located outside of Moncks Corner. Highway 52 spans the canal, and to the south, is Dennis Boat Landing. Santee Cooper has signs posted to dissuade would-be swimmers from entering the dangerous waters.
What is the difference between headrace and tailrace in a hydroelectric power plant?
The used water is released through the tail race. The difference between head race and tail race is called gross head and by subtracting the frictional losses we get the net head available to the turbine for generation of electricity.
Is Francis turbine mixed flow?
The Francis turbine is a mixed flow-type turbine in which the water passes through the curved guide vanes and creates a high curved rotational flow at the outlet. These turbines are generally suitable for a medium head with moderate discharge.
Which is part of the turbine is called the tail race?
The channel into which the turbine discharges in case of impulse wheel and through draft tube in case of reaction turbine is called a tail race. The suction pipe or draft tube is nothing but an airtight tube fitted to all reaction turbines on the outlet side.
How is tail race used in hydroelectric dams?
Tail race. Figure 1. A tail race channel on a hydroelectric dam. The tail race, containing tail water, is a channel that carries water away from a hydroelectric plant or water wheel. The water in this channel has already been used to rotate turbine blades or the water wheel itself.
What is the purpose of the tail race?
The tail race, containing tail water, is a channel that carries water away from a hydroelectric plant or water wheel. The water in this channel has already been used to rotate turbine blades or the water wheel itself. This water has served its purpose, and leaves the power generation unit or water wheel area. In hydroelectric…
What are the different types of turboprop engines?
Two basic types of turboprop engine are in use: fixed turbine and free turbine. The fixed turbine has a mechanical connection from the gas generator (gas-turbine engine) to the reduction gear box and propeller. The free turbine has only an air link from gas generator to the power turbines.
