Last Assignment (Hager book Figure 6.3):
Pool Water Level 1780 masl; diameter of1st tunnel = 8 m; rectangular tunnel 4m x4m, outlet tunnel is 10 m diameter, length l1= 250m, l2(transition ??), l3=50m, l4=300m(d=10m). Tunnel is concrete; invert level of
tunnel is 1710 masl. Design shape of theinlet, for the setup determine the ratingcurve of the gate for Water level varyingfrom 1780 to 1740 every 10 m interval, and
for the gate opening from full, half, size 4m. Finally draw the hydraulic and energygrade lines for the case of WL at 1780m andfull gate opening. Also indicate the type offlow you have in the outlet tunnel for the
case of WL 1780 and gate fully opened.
