MCOB, PHASE II Calculation: C-2 Page 5 WEIR WALL HEIGHT CB 13: Not full flow Step 5&6: use Flowmaster to fill in normal depth,critical depth,velocity head Step 7: Case F: Face depth= EGLa-BOCo=423.60-422.4=1.2 Face velocity head =0.74 Ho=0.4*face velocity head=0.4*0.74=0.296 EGLo = Ho+ EGLa =0.296+423.60=423.90 HGLo= EGLo-velocity head (8A) =423.90-.21=423.69 Step 8: Case B flow is supercritical, continue to step 9 Step 9: set pipe loss to 0 Step 10: Set HGLi and EGLi and skip to step 15. Step 16:Check for supercritical flow;Set Eaio to zero,flow is supercritical Step 17, 18, 19: No benching, angles, or plunging CB 70: Not full flow Step 5&6: use Flowmaster to fill in normal depth, critical depth,velocity head Step 7: Case F: Face depth= EGLa-BOCo=424.47-424.04=0.43 Face velocity head =0.49 Ho=0.4*face velocity head =0.4*0.49=0.196 EGLo = Ho+ EGLa =0.196+424.47=424.67 HGLo= EGLo-velocity head(8A)=424.67-.21=424.46 Step 8: Case B flow is supercritical, continue to step 9 Step 9: set pipe loss to 0 Step 10:Set HGLi and EGLi and skip to step 15. Step 16: Check for supercritical flow;Set Eaio to zero,flow is supercritical Step 17, 18, 19: No benching, angles, or plunging CB 14: Not full flow Step 5&6: use Flowmaster to fill in normal depth, critical depth,velocity head Step 7: Case B: EGLa<BOCo+dc;425.07<424.9+.25;425.07<425.15 Ho=0 EGLo =d+Velocity head+BOCo=424.9+.19+.2=425.29 HGLo=d+BOCo=0.19+424.9=425.09 Step 8: Case B flow is supercritical, continue to step 9 Step 9: set pipe loss to 0 Step 10: Set HGLi and EGLi and skip to step 15.
