Flow coefficients of Roots pump exhaust duct were calculated in a wide range of Reynolds numbers with the help of hydraulic gas dynamics numerical methods. Comparison with experimental data verified adequacy of obtained results. Approximation relationship mass flow coefficient vs rotor rotation angle is obtained which can be used for mathematical models of Roots pumps.
