A sluice gate, which controls flow rate in a channel by simply raising or lowering a vertical plate, is commonly used in water irrigation systems. A force on the gate due to the difference between the water heights y₁ and y2 and the flow velocities V₁ and V₂ upstream and downstream from the gate, respectively. For simplicity we may assume inviscid (frictionless) water flow. Obtain the horizontal force exerted by the flow on the vertical plate if y₁ =10 ft and y₂ = 3 ft. Take width of the sluice gate (into the page) to be w = 5 ft.

A sluice gate, which controls flow rate in a channel by simply raising or lowering a vertical plate, is commonly used in water irrigation systems. A force on the gate due to the difference between the water heights ??1 and ??2 and the flow velocities ??1 and ??2 upstream and downstream from the gate, respectively. For simplicity we may assume inviscid (frictionless) water flow. Obtain the horizontal force exerted by the flow on the vertical plate if ??1 =10 ft and ??2 = 3 ft. Take width of the sluice gate (into the page) to be ?? = 5 ft.

4. A sluice gate, which controls flow rate in a channel by simply raising or lowering a
vertical plate, is commonly used in water irrigation systems. A force on the gate due to
the difference between the water heights y, and y2 and the flow velocities V, and V2
upstream and downstream from the gate, respectively. For simplicity we may assume
inviscid (frictionless) water flow. Obtain the horizontal force exerted by the flow on the
vertical plate if y, =10 ft and y2 = 3 ft. Take width of the sluice gate (into the page) to be
