發問:
permitted leakage(formule) = 0.02*d *l *t/24*P/10 litre P是怎來的, 我知consultant / WSD是知,他是利用什麼得出? 請用中文答 thk...
最佳解答:
Calculation : The permitted leakage of water from the pipeline during the pressure test shall be calculated from the equation: Permitted leakage = 0.02 x d x l x t x P litre where: - d is the nominal diameter of the pipe (mm) - l is the length of pipeline tested (km) - t is the test period (hr) - P is the average test pressure (m) 但"P"只不過一個系數 (每一米可容許漏幾多升水), 因為"P"是要成反水管長度, 方可得出"可容許之漏水量" (就是幾多升水). 你可以去以下網子睇吓: http://www.cedd.gov.hk/eng/publications/standards_handbooks/doc/stan_gs_2006/gs_2006edt_vol_2_120608.pdf
