A bar rack is inclined at 30 angle with the vertical. The rectangular bars are %" "(inch) wide in the dimension facing upstream as shown in Figure QI. The approach velocity (v) is 1.37m/s for a total flow of 0.85m3/s. The depth of channel is 0.61m. Figure Q1: Bar-screen Determine : i) area (A) and width of the channel in m2 and m respectively, ii) bar sereen cross sectional area (A) in m2, iii) open area of bar-sereen (Akc) in m2, iv) velocity through sereen (W) in m/s, v) number of bars in the screen and vi) head loss through the screen in m
