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 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 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 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 unit of steam flow in turbine?
kg/s
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.
How energy is being transformed when turbine is spinning?
pressure/flow of the median(water/exhaust) is converted into mechanical torque on the shaft by the turbine.
How do you lower turbine differential expansion?
by controlling main steam flow
How the liquid flow meter is working?
The turbine flow meter translates the mechanical action of the turbine rotating in the liquid flow around an axis into a user-readable rate of flow. The turbine tends to have all the flow traveling around it. The turbine wheel is set in the path of a fluid stream. The flowing fluid impinges on the turbine blades, imparting a force to the blade surface and setting the rotor in motion. When a steady rotation speed has been reached, the speed is proportional to fluid velocity. Turbine flow meters are used for the measurement of natural gas and liquid flow
