n Bar Racks h. L = headloss, ft (m) 0. 7= an empirical discharge coefficient to account for turbulence and eddy losses V = velocity of flow through the openings of the bar racks, ft/s (m/s) v = approach velocity in upstream channel, ft/s (m/s) 2 (m/s 2) 2. Pretreatment g = acceleration due to gravity, ft/s 16
n Fine Screens h. L = headloss, ft (m) C = coefficient of discharge for the screen (typical value for a clean screen = 0. 60) g = acceleration due to gravity, ft/s 2 (m/s 2) Q = discharge through screen, ft 3/s (m 3/s) A = effective open area of submerged screen, ft 2 (m 2) 2. Pretreatment 17
