Catenary is the curve formed by the Turbine Rotors when they are placed on their respective Bearings.The level of each bearing and its housings are ear marked or indicated by the manufacturer of turbines.At the time of erection this is to be followed by laser alignment or by piano wire,water level etc

What is HP and LP turbine expansion?
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
What is the wheel chamber pressure in turbine?
Resistance offered by turbine to the steam
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.
What is tenon in steam turbine?
It is what attaches the shroud to the turbine blades
What is turbine runback?
Controlled unloading of a turbine operating under load.
What is catenary in steam turbine?
generally more than three shafts contact by coupling together in steam turbine. the shaft is heavry and will be sag. in order to reduce the bend force on coupling and bend force on bearing, the engienering calclated the shaft and simulated when its in operation condition. so, the catenary curve and bearing elevation data have been provided for steam turbine installation.
What is sag in transmission lines?
Catenary
Expressions used in catenary taping?
5
What is the formula in calculating catenary?
The general formula of a catenary is y = a*cosh(x/a) = a/2*(ex/a + e-x/a) cosh is the hyperbolic cosine function
What is the strongest shape underground Catenary or Hemisphere?
sphere
What is a equation for a catenary with a 2?
A equation is santa clause
What are the similarities between parabola and catenary?
The Catenary and Parabola are different curves that look similar; they are both "U" shaped and symmetrical, increasing infinitely on both sides to a minimum.
What is catenary towing?
A catenary is the curve formed by slack wire - telephone cables are a good example. So a catenary tow is one where, simply put, the towline is attached to shackles of anchor cable in order to ensure that a belly of towline (providing spring) hangs between the two ships.
What is the Formula for sag in a catenary?
If: A=Horizontal distance betwen ends (at same height) B=Depth of catenary C=radius of curvature at lowest point L=length along catenary M=Mass per unit length Tm=Tension at ends of catenary To=Tension at lowest point. (Also horizontal component of tension at any point) Then: C=To/M, and B=C(cosh(A/2C)-1)
What is catenoids?
A catenoid is the surface generated by rotating a catenary about its axis of symmetry
How are the catenary arch and parabolic arch different?
A catenary is produced by hanging a chain from two points some distance apart. The equation for a catenary is the hyperbolic cosine. One simple example of a catenary can be found if you look at the power lines running between two poles. A parabola is produced by putting a hanging chain or cable under an equally dispersed load. An example of this can be seen on a suspension bridge, the cable hanging from two towers with the road below hanging from vertical cables attached to the main suspension cables.
What surface is formed when you rotate a catenary about its vertical axis?
apparently, it is called catenoid.
