  1. The impacts of both the velocity head and momentum distribution in the t - junction of a tailrace surge tank on the critical stable sectional area of the tank were analyzed by using gardel ' s empirical equations for t - junction flow. based on thoma ' s theory, a formula of the critical stable sectional area is derived. 5

    基於gardel關於三通管水頭損失的經驗公式,研究分析了連接管處的速度水頭以及進出調壓室水體與尾水隧洞水體之間的動量交換,對有連接管的尾水調壓室穩定斷面積的影響,並在托馬( thoma )假定基礎上,推導出相應的調壓室穩定斷面的計算公式; 5
