Flow area equation

WebThe area of the water as it flows through the chute is 0.240 m 2. The flow rate can be found in m 3 /s using the formula: Q = Av. Q = (0.240 m 2)(5.00 m/s) Q = 1.20 m 3 /s. The flow rate can be converted to liters per second using: 1 m 3 /s = 1000 L/s. Q = 1200 L/s. The flow rate of the water in the chute is 1200 L/s. http://irrigation.wsu.edu/Content/Calculators/Residential/Garden-Hose-Flow.php
