Step 3 CALCULATE DISCHARGE

Cross-sectional area of wetted stream (m²)
Discharge Wetted Width: 9.400			Discharge Average Depth: 0.290			= 2.726
Average Time (sec)
16.700	16.600	16.700	16.600	16.700	83.3		16.66
Trial 1	Trial 2	Trial 3	Trial 4	Trial 5	Total Trials	/ 5	Average Time
Average Velocity (sec)
10.000			16.66			0.600
Length (m)			Average Time (sec)			Average Velocity (m/sec)
Average Stream Discharge (m³/sec)
