How do you calculate flow rate
WebMar 28, 2024 · To calculate the flow rate of fluid passing through an orifice: Multiply the gravitational constant, g, with the mean centerline, H. Multiply the result with 2. Find the square root of that product. Multiply the resultant with the area of orifice, A, and the coefficient of discharge, Cd. WebIf you don’t know the flow rate, estimate it by holding a pan or bucket under the faucet or shower head and measure the flow for a minute. The flow rate through the demand water heater should be at least 3.25 gallons (12.3 liters) per minute. To reduce flow rates, install low-flow water fixtures.
