What is steam velocity in turbine?
That is how fast the steam is actually moving in the turbine. For impulse turbines it is twice as fast as the turbine blades. In reaction turbines it is the same speed as the blades. Because the blades of a turbine cannot move faster than 4500 feet per second without self destructing as it overcomes the centripetal force of the turbine wheels, the steam turbine is designed such that no turbine will exceed more than ~1150 feet per second on its tip speed. Thus the steam velocity through the turbine will be less than ~1150 fps for a reaction turbine and less than ~2300 fps for an impulse turbine, or about ~1570 mph, more than twice the speed of sound.
What is the difference between Bucket and Vanes?
Bucket is having an angle of deflection of a jet more than 90 degree where as vane is having less than 90 degree. Bucket can generate an IMPULSE FORCE only whereas vane can generate both IMPULSE and REACTION FORCE both. by PRIYANSHU SRIVASTAVA MECHANICAL ENGINEER
Is the impulse produced by a larger force always greater than the impulse created by a smaller force?
I believe the answer is no. The impulse produced is also time related. Impulse force is measured as dp/dt. Therefore a smaller force produced for a very quick time could produce a larger impulse than a large force over a longer time.
What is a wave turbine?
Horizontal axis wind turbines, modern wind turbines, vertical axis turbines.
What is the effect on a steam turbine if the system is running in under frequency?
It results in reduced ventilation and affect the turbine more than the generator.
How do you make sentence for word impulse?
An impulse is a sudden strong urge or desire to act on a whim, often without careful thought or consideration. It is important to carefully evaluate our impulses before acting on them to avoid potential consequences.
Is the velocity of a nerve impulse greater than electrical conduction's?
yes
What is turbine windage protection?
when steam flow blockage occured in steam turbine due to damage of blades/nozzles than steam temperature will increase so protect the turbine from high temperature this protection is introduced.
Why deaerator is placed at a higher level than turbine?
Your question is very Bad should you know the dearator in water cycle and turbine in steam cycle
What makes a wind turbine work other than wind?
lolol
What are the advantages of free turbine engine over gas turbine engine?
A gas turbine engine will usually yield more power by weight than a piston engine. Main downside is that it can't be throttled very well. Energy efficiency isn't all that good to start with, and will drop right down if it has to be operated outside its optimum range.
Is it possible to attach a wind turbine to an airplane to increase efficiency?
No. The amount of energy gained will be less than spent by the aircraft to overcome the drag created by your turbine.
