Computation

Horsepower Lab 2D
$55.00 - Horsepower Lab Software

Package for numerical computation of compressible flows through local flow restrictions. It determines pressure losses and discharge coefficients with account for compressibility effects, for flows at high Reynolds (Re) number and for restriction shapes restricted to 2D. More accurate results are for restrictions with "geometrically" induced flow separation, i.e. where more or less sudden flow contraction/expansion occurs.

The Calculator
Free - Delta-Z Software

The value suffixes is one of the most interesting features of The Calculator. So, if you need to enter a 4 000 000, just type 4M. That's all! Need to calculate the cosine of 20 degrees? (By default, The Calculator works with radians) Type cos(20g) and get the result.
