WebThe metric unit m 3 /s is referred to as the cumec. Because m 3 /s is a large unit, smaller flows are measured in litres per second (l/s). A simple way to estimate the velocity is to measure the time taken for a floating object to travel a measured distance downstream. http://stream1.cmatc.cn/pub/comet/HydrologyFlooding/streamflow/comet/hydro/basic/Routing/print_version/04-stream_properties.htm
Discharge (hydrology) - Wikipedia
Web12 Jun 2024 · Discharge is the volume of water moving down a stream or river per unit of time, commonly expressed in cubic feet per second or gallons per day. Why is stream flow important? Streamflow information is required to determine how much water is available in different locations so the citizens can make informed decisions about growth and to help … Web20 May 2024 · To obtain the rate of flow , this average velocity ( measured velocity x co-efficient) is multiplied by the average cross sectional area of the stream. Discharge or rate of flow = area x velocity Q = A X V where Q= discharge rate in m3/sec. v = velocity of flow in m/s a = cross section al area of channel in m2. b) Water meters: new york state homeschooling laws

Web19 Jun 2024 · Discharge measures are typically not exact anyway, and +- 10% considered good. So if you measured discharge during a stable flow day, at all the cross sections, there would probably some... WebTwo measurements of the discharging jet are required to calculate the rate of flow of the water. The first measurement is the horizontal distance, “X”, (parallel to the centerline of the pipe) required for the jet to drop a vertical distance “Y” which is the second measurement. WebDischarge or Flow Rate. Discharge (also called flow rate) The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate. new york state hospital association
