Measure the flow of irrigation water
WebWe calculated the flow rate at 780 gallons per minute and the total irrigation time at 4635 minutes. Using Equation 8.3: Depth pumped (d p ) = [ Flow rate x time ] / [ Area irrigated x 27,154 ] Depth pumped (d p ) = [ 780 gal/min x 4635 minutes ] [ 123 acres x 27154 gal / ac-in ] WebApr 12, 2024 · Cracking in wading-concrete structures has a worse impact on structural safety compared with conventional concrete structures. The accurate and timely monitoring of crack development plays a significant role in the safety of wading-concrete engineering. The heat-transfer rate near a crack is related to the flow velocity of the fluid in the crack. …

WebJun 13, 2024 · In the simplest method, a current meter turns with the flow of the river or stream. The current meter is used to measure water velocity at predetermined points (subsections) along a marked line, suspended cableway, or bridge across a river or stream. The depth of the water is also measured at each point.
WebFlow is measured using a staff gauge (see lower left), placed in the . channel far enough above the struc-ture so it is unaffected by the curve of the water over the weir.
