For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).Ĭubic feet per second ( cfs): * 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water. The SI unit for flow rate is m 3/s, but a number of other units for Q are in common use. Q=Vt Q = V t, where V is the volume and t is the elapsed time. Similarly, you may ask, what is the formula for flow rate? gallons per minute 4.42 acre-feet per day Metric Equivalents 15 million gallons per day (mgd) 56.775 megaliters pr day (ML/day) 1 acre. One may also ask, how much is a cubic foot per second? Cusec is a measure of flow rate and is informal shorthand for " cubic feet per second" (28.317 litres per second). 1 million gallons per day (mgd) 1,120 acre feet per year 1000 gallons per minute 2. You can view more details on each measurement unit: million gallon/day or cfs The SI derived unit for volume flow rate is the cubic meter/second. Bigger pipe is more expensive, but keeping the water velocity low is important to limit pressure losses due to friction, water hammer, and pipe movement due to water momentum changes inside the pipe. Used to calculate the velocity of water in a pipe. We assume you are converting between million gallon/day and cubic foot/second. Pipe Water Velocity and Minimum Pipe Diameter.

In this regard, how do you convert CFS to MGD? * 1 cfs is equivalent to 448.8 gallons of water flowing per minute. * 1 cfs = 1.983 acre-feet per day = 646,320 gallons = 2447 cubic meters of water. * 1 cubic foot per second = 7.4805 gallons flowing by a particular point in 1 second. EXAMPLE Q R 325 cfs Q P 3. 0.9 Factor to reserve of 10 percent of rivers assimilative capacity. Q P Discharge rate, in million gallons per day (mgd). Cataract surgery may aggravate the signs of MGD, and the severity of MGD may positively correlate with TBUT, CFS, and corneal lesions after surgery. R Estimated 7Q10 low flow for the receiving water at the outfall, in cubic feet per second (cfs). Learn more about the units used on this page.Cubic feet per second ( cfs): * 1 cubic foot = 7.4805 gallons. Thus, patients with MGD may have a greater chance of developing the dry eye disease after cataract surgery. For example larger friction losses in a pipe going downhill may be allowable or even desirable. This 5 ft/sec threshold is a simple method of selecting pipe size, but a better method is to use allowable pressure losses due to friction and elevation change and to include protections against water hammer and pipe movement in the trenches (blocking). Example The flow entering the grit channel is 2.95 MGD. to MGD a) 2.71 MGD b) 27.1 MGD c) 65.1 MGD d) 6.51 MGD. 5 ft/sec is a somewhat arbitrary velocity threshold that some designers use because beyond that the friction losses, danger of water hammer, and pipe movement due to water momentum changes are deemed to be too high. MGD to cfs From the table: MGD 1.55 Cubic feet/second cfsMGDx1.55cfs/MGD. Use the second form to calculate the inside diameter of a pipe at a water velocity of 5 ft/sec. Pipe Water Velocity and Minimum Pipe Diameter
