STATISTIC - ALGORITHMS

Statistics - algorithms

There are algorithms used in some formulas in Drafter's statistic module.

Volume:

Excavation volume is calculate as sum of volumes:
  • sections:

    V1 = H x (S1+S2)/2 x L [m3]

    where:
    V1 - one section volume,
    H - averaged depth of pipe bottom increased by bedding layer height,
    L - section length.
  • tanks that exists in profile, like a: septic tanks, biofilters, separators etc.:

    V2 = H x (S + Rx2) x (L + Rx2) [m3]

    where:
    V2 - one tank volume,
    H - averaged depth tank bottom increased by bedding layer height,
    S - tank width,
    L - tank length,
    R - width of additional hollow (menu: Tools > Configuration > Cross-section).
  • sumps:

    V3 = H x (D + Gx2 + Rx2) [m3]

    where:
    V3 - one sump volume,
    H - averaged depth sump bottom increased by bedding layer height,
    D - sump diameter,
    G - sump wall thickness (menu: Tools > Configuration > Cross-section),
    R - width of additional hollow (menu: Tools > Configuration > Cross-section).
