Dimensional Analysis and Dimensionless Numbers

Overview

Engineering reference data for Dimensional Analysis and Dimensionless Numbers in basics.

Key Formulas

Ohm's Law

$V = IR$

Voltage = Current × Resistance.

Newton's Second Law

$F = ma$

Force = mass × acceleration.

Conservation of Energy

$E_{in} = E_{out} + \Delta E_{stored}$

Energy balance.
