Nq bearing capacity factor
Karl von Terzaghi was the first to present a comprehensive theory for the evaluation of the ultimate bearing capacity of rough shallow foundations. This
Suction head coefficient
NPSH characterize the potential for cavitation. The suction head coefficient is a dimensionless measure of ... more
Internally Tangent Circles
Two circles of non-equal radius, both in the same plane, are said to be tangent to each other if they meet at only one point.
Two circles are
Ripple factor (choke)
For the root mean square value of the ripple voltage, the calculation is more involved as the shape of the ripple waveform has a bearing on the result.
