Conclusions

  1. 1.

    The values of the initial coefficients of discharge for double-bevel diaphragms were determined for moduli of 0.0905, 0.1624, 0.2504 and 0.3694 in the Re range of 240 to 1900.

  2. 2.

    The root-mean-square error of the initial discharge coefficient did not exceed 0.18%.

  3. 3.

    The relation ofα u=f(m; Re) derived in the article makes the calculation of double-bevel diaphragms possible for Re values between 240 and 1900.
