Introduction

Laplace's equation
Laplace's equation is a partial differential equation. Partial differential equations (PDE) are a type of differential equation, i.e., a relation involving an unknown function (or functions) of several independent variables and their partial derivatives with respect to those variables. Partial differential equations are used to formulate, and thus aid the solution of, problems involving functions of several variable ....etc

If the secondary coil is attached to a load that allows current to flow, electrical power is transmitted from the primary circuit to the secondary circuit.Ideally,the transformer is perfectly efficient; all the incoming energy is transformed from the primary circuit to the magnetic field and into the secondary circuit. If this condition is met, the incoming electric power must equal the outgoing power.
Pincoming = IPVP = Poutgoing = ISVS

giving the ideal transformer equation

The Radar Equation


Introduction


Before target information can be extracted from an echo signal, that signal must be of sufficient magnitude to overcome the effects of interference.
The radar equation is used to predict echo power and interfering power to assist in making the determination of whether or not this condition is met. Use of the radar equation accomplishes the following:

Assists in the design of radar systems to meet the detection specific ....etc

Procedure:-
1. Rewrite the given difference equation to have only the output terms on the LHS and input terms to be on RHS
2. Create a Matrix of Y coefficients, a
3. Create a Matrix of X coefficients, b
4. Generate the input sequence x(n)
5. Find the output of the system for the input sequence x(n)
6. Plot the input and the output

sir,
i need a ppt sugesting some useful equations which would help me to find the power ratings of the motor which can be used to drive a roots type blower for pneumatic conveyor applications.I have to transport TiO2 powder to a horizontal distance of 10 m,then vertically up through 25 m and dump it in a tank there.The pipeline used is nearly 6inch in diameter. and the discharge requirements is 7200kg/hr.
Please help me...
Thanking You,
