Engineering Calculators

Metals Weight Calculator :

Calculate weight of metal based on alloy type and shape.

Flow Rate Calculator :

This flow rate calculator uses flow velocity and cross-sectional flow area data to determine the volumetric flow rate of liquid.

Friction Loss Calculator :

This Calculator employs the Hazen-Williams equation to calculate the pressure or friction loss in pipes. Losses are calculated on the basis of flow rates in circular pipes, the internal diameter of the pipe, the length of the pipe, and the type of pipe.

Resistor Color Code Calculator :

The electronic color code was established to make it easier to recognize the values of resistors and other components. This calculator allows users to determine the value of a resistor based on the color code but also find the color codes for a 4 and 5 band resistor.

Voltage Divider Calculator :

You can use this voltage divider calculator to determine any one of the four variables associated with a simple two-resistor voltage divider when the values of the other three variables are available. The four variables involved in a two-resistor voltage divider are input voltage, output voltage, resistance 1, and resistance 2.

RMS Voltage Calculator :

Determine the root mean square (RMS) voltage values of the most frequently employed periodic waveforms; for example, sine wave, triangle wave, square wave, and others.

Wheatstone Bridge Calculator :

This calculator is designed to help calculate missing resistor values (R4) for balanced bridges (Vb = 0). The calculator can also provide you with the voltage across the bridge (Vb), if you provide the resistor values (R1, R2, R3, R4) and input voltage (Vin).

Resonant Frequency Calculator :

This calculator employs the capacitance (C) and inductance (L) values of an LC circuit (also known as a resonant circuit, tank circuit, or tuned circuit) to determine its resonant frequency (f).

Transformer Calculator :

This calculator quickly and easily calculates the primary and secondary full-load currents of the transformer. It also determines the turns ratio and type of transformer.

Motor Full Load Amperage Calculator :

This MFLA calculator helps you to calculate the full-load current of the AC electric motor.

Power to Weight Ratio (PWR) Calculator :

This calculator provides a quick and easy way to determine the power-to-weight ratio (PWR) of any vehicle.

Quarter Mile Calculator :

Determine the terminal speed (trap speed) and quarter-mile elapsed time (ET) of a vehicle based on its weight and power.

Compression Ratio Calculator :

The compression ratio of an engine is a very important element in engine performance. The compression ratio is the ratio between two elements: the gas volume in the cylinder with the piston at its highest point (top dead center of the stroke, TDC), and the gas volume with the piston at its lowest point (bottom dead center of the stroke, BDC). This compression ratio calculator can be used to work out the compression ratio of your engine.
