What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
What is difference between pelton wheel and turgo turbine?
pelton turbine is used for high head low flow but the turgo turbine is used for low head high flow, in pelton turbine number of jet can increased but in turgo it can't be done, in pelton the water hits the bucket once at a time but in tugo it hits more than one
Which device controls the speed of the turbine shaft?
The device which control the speed of Turbine is Governor. The Governing system sense the speed of shaft & regulate the Fuel/ Motive fluid flow to the Turbine to maintain the set shaft speed.
What is the differences between pelton turbine and kaplan turbine?
pelton turbines are suited to high head,low flow application but kaplan turbine are used for low head and a large amount of discharge needed. kaplan turbines are expensive to design,manufacture and install as compared to pelton turbine but operate for decades.
The turbine which rotates in only one direction whether the flow of wind is in either direction what is the name of this turbine?
i have got a pic of such turbine this is designed by some engineering studentshere is the picturehttp://www.engin.umich.edu/dept/name/research/projects/wave_device/picture005.jpg
What is tangential velocity of turbine?
Tangential velocity of a turbine refers to the linear speed of a point on the edge of the turbine’s rotor as it moves in a circular path. It is calculated using the formula ( V_t = r \cdot \omega ), where ( V_t ) is the tangential velocity, ( r ) is the radius of the rotor, and ( \omega ) is the angular velocity in radians per second. This velocity is crucial for determining the efficiency and performance of the turbine, as it impacts the energy conversion process. Higher tangential velocities often lead to greater energy output, provided the turbine is designed to handle such speeds.
What is difference between radial flow turbine and axial flow turbine?
in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.
Why velocity of flow will decrease with increase in peripheral speed of francis turbine?
the peripheral velocity of the turbine is the around velocity. the increase in the velocity of the peripheral will decrease the velocity of the flow towards the turbine
What is a advantages and disadvantages of Francis turbine?
The inward flow reaction turbine having radial discharge at outlet is called Francis turbine
What are the common types of force acting on a wind turbine components?
centrifugal force,gravitational force,gyroscopic effects,tangential forces, torque,shear forces
What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
What is unit of steam flow in turbine?
kg/s
What is surge pad of steam turbine?
A surge pad in a steam turbine is a component designed to manage and stabilize the flow of steam within the turbine system. It helps prevent excessive pressure fluctuations and maintains a consistent flow, which is crucial for optimal turbine performance and efficiency. By providing a buffer against sudden changes in pressure or flow, surge pads contribute to the overall reliability and safety of the steam turbine operation.
What is the critical flow area inside the turbine housing of a turbocharger known as?
The critical flow area inside the turbine housing of a turbocharger is known as the "turbine inlet area" or "turbine nozzle area." This area is crucial for optimizing exhaust gas flow into the turbine, influencing the turbocharger's efficiency and response. Proper sizing and design of this area help to maximize the energy extracted from the exhaust gases, ultimately enhancing the performance of the engine.
What is hydrolectricity?
electricity created by the flow of water turning a turbine
Why draft tube is used in francis and kaplan turbine and not in pelton turbine?
The Kaplan turbine is a newer, more revolutionary version of the Francis turbine, which came before it. The draft tube is used so that the turbine does not need to be where the water flow is lowest.
Working princieple of Francis turbine?
It is a radial flow axial turbine . It works on the principle to convert pressure energy into kinetic energy.
