Praveen Reddy - August 10, How can we decide the copper thickness of a track? Generally, what are the guidelines for copper thickness on power supply boards? Brad - August 10, Praveen, Copper thickness can be traded against width.

In fact it was often a necessary evil.

With the advent of the VFD you may be able to achieve relatively constant flows and reduce the energy required. This tutorial investigates the possibilities. This tutorial uses a constant pressure application to show you the proper way to do that comparison.

Return to Titles Variable Frequency Control - Other Advantages VFD's can reduce energy consumption by allowing a pump to run at the duty point required by the system and it can change that duty point in real time. But they offer several other advantages that can often justify their use even if pump speed is not varied.

This tutorial explores those other advantages. That is how it varies the motor speed. But, did you know that it must also vary the voltage? If it did not, the magnetic field produced by the stator would become saturated and torque would become unreliable.

Resonance arrises when a variable speed pump reaches a critical speed. It turns out that the first or lowest critical speed can be easily calculated from simple data provided by the manufacturer.

This tutorial explores resonant frequency and shows how to calculate the speed that causes it.Point slop is one of the method used to find the straight line equation.

Use the below point slope form calculator to calculate the equation of the straight line by entering the value for slope and coordinate point (X1, Y1).

This calculator can find the center and radius of a circle given its equation in standard or general form. Also, it can find equation of a circle given its center and radius. The calculator will generate a step by step explanations and circle graph.

Introduction.

Sharpness is arguably the most important photographic image quality factor because it determines the amount of detail an imaging system can reproduce.

It’s not the only important factor; Imatest measures a great many others. Sharpness is defined by the boundaries between zones of different tones or colors.

Slope intercept form is the more popular of the two forms for writing equations. However, you must be able to rewrite equations in both forms. For standard form equations, just remember that the A, B, and C must be integers and A .
