What is zero sequence impedance in transmission line?
In symmetrical components, there are three types of impedances - positive sequence (balanced), negative sequence (unbalanced), and zero sequence (ground). In a transformer, positive and negative are equal. Ground impedance is determined by the (same factors as the) positive sequence and is based on the flux paths available through the transformer core that can induce ground current.
What is inheritance in JAVA programming?
Inheritance in JAVA programming is the process by which one class takes the property of another class. The new classes, known as derived classes or subclasses, take over the attributes and behavior of the pre-existing classes, which are referred to as base classes or super classes. It helps the programmer to re-use the class just by modifying minor objects and methods in it. class person { attribute-name,address } class Emp extends person { attribute-(same as parent class)name,address own attribute-salary(modification) }
How can the star and delta connections be combined to produce a star delta starter for an electric motor?
It depends on the motor. You need to look at the specifications of the particular motor. In general, if there are only three conductors, not counting earth, then it is delta; if there are four, then it is star; if there are six, then it is star-delta and you need a star-delta starter.
What is piezometric pressure?
Piezometric pressure is the simplest form of the hydrostatic equation in fluid mechanics. Simply put, the hydrostatic equation is the following: P + (gamma)*z = constant (I apologize but I wasn't able to insert greek letters.) where, P = pressure. gamma = specific weight (assume constant; fluid is incompressible unless it is a gas) z = sometimes called piezometric head or pressure head. It is simply the elevation or the vertical distance (height) from a fixed reference point called a datum. The whole left side expression of the equation is the piezometric pressure, Pz In order to use this equation in fluid mechanics, you must define 2 points of analysis and plug the variables. P1 + [(gamma)*z1] = P2 + [(gamma)*z2] When dealing with a fluid in motion, however, the piezometric pressure is no longer constant in the system. Partial derivatives and acceleration get involved. The resulting equation is know as Euler's Equation. Hope this is enough help!
What are pump fundamentals?
Pump fundamentals are the fundamental principles that govern how pumps work. These include the conservation of mass, mechanical energy, and momentum which is often restated in the form of the Bernoulli equation:(P2-P1)/rho+g*(z2-z1)+0.5*(V2^2-V1^2)+ef+w=0for incompressible systems in turbulent flowP2= outlet pressureP1= inlet pressurerho= densityg= gravitational constant = 9.81m/s^2=32.174ft/s^2 on earth at sea levelz2= final heightz1= initial heightV2= outlet velocityV1= inlet velocity (often equal to zero if you are pumping a stationary fluid)ef= frictional force (summation of all friction due to pipe lengths, fittings, valves, expansions, and contractions)w= work (in this case w>0 means work flows out of the system)The continuity equation is useful when dealing with flowing fluids and is simply a restatement of conservation of mass:(rho*V*A)in=(rho*V*A)outA= cross sectional area
What formula with functions in Excel can you enter to calculate the ratio of the maximum value in the range Z1 to Z10 to the minimum value?
=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)=MAX(Z1:Z10)/MIN(Z1:Z10)

If ZZ1Z2 and Z3 are complex no.s such that Z1-ZZ2-ZZ3-Zthen show that Z1Z2 and Z3 lie on a circle with centre at Z.?
If Z,Z1,Z2 and Z3 are complex no.s such that |Z1-Z|=|Z2-Z|=|Z3-Z|,then show that Z1,Z2 and Z3 lie on a circle with centre at Z.
How do you convert Pi-network to T-network?
Any pi network can be transformed to an equivalent T network. This is also known as the Wye-Delta transformation, which is the terminology used in power distribution and electrical engineering. The pi is equivalent to the Delta and the T is equivalent to the Wye (or Star) form. Pi NetworkT Network The impedances of the pi network (Za, Zb, and Zc) can be found from the impedances of the T network with the following equations: Za = ( (Z1*Z2)+(Z1*Z3)+(Z2*Z3) ) / Z2 Zb = ( (Z1*Z2)+(Z1*Z3)+(Z2*Z3) ) / Z1 Zc = ( (Z1*Z2)+(Z1*Z3)+(Z2*Z3) ) / Z3
