Consider a weir constructed in a river having a width of 9m for raising its water level to 12m as shown in the figure. The velocity of water upstream of the weir is 30 cm/s. Water flows down the weir with a uniform thickness of 1m. Determine the horizontal force on the weir by assuming that the flow is steady and frictionless.
