I will be discussng about DC generators

Principle of DC generators

  • The aim of a generator is to convert mechanical power into electrical power and to do that we use Faraday 's law principle which says that rate of change of flux induces induced voltages ".So In order to achieve that we use following
  • A Magnetic flux which is provided by two magnets and direction is from north (N) to south (S).
  • A conducting coil which can rotated in that flux.which will produce changing magnetic flux and so induced voltage
  • Now, with the help of any mechanical energy in any way like due potential energy of water in a dam , or pressurised steam in a thermal plant, rotate the coil and by that we can have E.M.F generated.

Coal is burned at an electric power generation plant at a rate of 150 kg/minute with 8% excess air (dry). The coal has a composition (mass based) of xC (kg C/coal), xH (kg H/coal), xS (kg Sulfur/coal) and xash (kg ash/coal). The coal produces 20 kg/minute of ash. The outlet gases, on a dry basis (i.e. we exclude any water from the calculation), have the composition (volume basis): yCO2=0.1418, yCO=0.024, ySO2=0.003, yO2=0.027, yN2=0.8042. Calculate the coal composition, air demand and...

What is the definition of magnetic flux? What is Faraday's Law? Can you use it effectively to find the currents induced by changes in magnetic flux? How can it be verified experimentally using a field coil and a pickup coil? If you know how the magnetic field changes in time in a field coil, can you determine how the current induced in a pickup coil will change in time?

Faraday's Law: What would you observe about the amplitude of an induced signal as the frequency varied? Describe whether the behavior is consistenent with Eq. 3 (Vo= w(Nd)A(Bo)cos(theta)). In particular what should your graph of amplitudes against frequencies look like according to Eq 3? In comparisons with the predictions of Eq 3, why would it be important to adjust the function generator to keep the amplitude of the B field the same at each frequency?

Newton's Law of Cooling is based on the principle that the rate of change of temperature y'(t) of a body in an environment with ambient temperature A is proportional to the difference b/w the temperature y(t) of the body and the ambient temperature A, so that y'=k(A-y) for some constant k. (1) Sketch the direction field for the equation y'=K(A-y) for k=1/10 and A=70degrees. Then sketch several solution curves based on starting values of y(0) both greater than and less...

Two methods can be used to produce solar panels for electric power generation. Method 1 will have an initial cost of $560,000, an AOC of $170,000 per year, and $115,000 salvage value after its 3-year life. Method 2 will cost $870,000 with an AOC of $115,000 and a $170,000 salvage value after its 5-year life. Assume your boss asked you to determine which method is better, but she wants the analysis done over a three-year planning period. You estimate the...
