Free Engineering
online Calculators
Welcome to the
free engineering online calculators page of our website.
ATTENTION!
If you have Java 2 platform installed, in order to properly use the
calculators, you have to disable <APPLET> Tag support which is enabled
by default. In order to do this, you have to:
1. Open the
control panel --> Windows Start / control panel
2. Click the Java
icon, to open the Java VM.
3. Click the
"Advanced" TAG, <Applet> tag support and disable the "Internet Explorer"
check box
4. The calculators
should be o.k.

NEW! addition.

You will find a
powerful units conversion program , Unit Master , which will convert
over 1000 units from 11 categories for you.
Darcy - Weisbach
calculator calculates friction loss over a pipeline , using the popular
Darcy Weisbach equation. Friction factor is computed by the program
using the Colebrook equation.
Heating piping is
another useful online calculator. You may calculate the water flow
required to transfer a given amount of heat energy and the vice - versa
, along with the pressure drop along the pipeline.
Water hammer
calculates the water hammer effect on a pipeline protected by an open
tank , or a air vessel absorber under pressure.
The voltage drop
calculator is yet another powerful electrical calculator. Besides the
voltage drop on a wire line which is calculated keeping in mind the
temperature influence and the inductance of the cable itself , you
may calculate the line current given the voltage and electric power to
transfer for 1 phase and 3 phase lines. You may also perform the reverse
calculation (given the available line current - calculate the maximun
electric power which can be feeded).
kVAR master is a
simple program to calculate the capacitors needed to correct cos(f) of
an installation.
Motor protection
is another calculator which will calculate the necessary motor
protection equipment for protecting an electric motor.
Finally motor
sizing is rather an active page than a calculator. You can find
equations to calculate motor sizes for various applications , and
perform automatic calculations.
