Horsepower Lab 2D - Version 0.96 Package for numerical computation of compressible flowsthrough local flow restrictions. It computes pressureloss coefficients and coefficients of discharge withaccount for compressibility effects, for flows at highReynolds (Re) numbers and restriction shapes limited to2D. More accurate results are obtained for restrctionswith "geometry-induced" flow separation, i.e. wheremore or less sudden contraction/expansion is present
