The spillway for the dam is 20 m wide and is designed to carry 125 m3/s at flood stage. A 1:15 model is constructed to study the flow characteristics through the spillway. The effects of surface tension and viscosity are to be neglected, determine the flow rate:

• A. 0.162 m3/s
• B. 0.151 m3/s
• C. 0.148 m3/s
• D. 0.143 m3/s
