In the vertical wall of a reservoir (A) there is a drowned hole that it flows into another reservoir (B) with a real discharge speed of 4,5m/s. This one reservoir (B), in turn, has a square orifice with free discharge of the form shown in the figure. It requires a flow of 0,089 m³/s and there is no overflow of the system, determine the head loss in both orifices. (See the image) Data: Orifice diameter 1 = 0,2m; Discharge coefficient for orifice 2 = 0,604; contraction coefficient for orifice 2 = 0,64. Consider both holes small in relation to the depth of the reservoirs.

Question

In the vertical wall of a reservoir (A) there is a drowned hole that it flows into another reservoir (B) with a real discharge speed of 4,5m/s. This one reservoir (B), in turn, has a square orifice with free discharge of the form shown in the figure. It requires a flow of 0,089 m³/s and there is no overflow of the system, determine the head loss in both orifices. (See the image)

Data: Orifice diameter 1 = 0,2m; Discharge coefficient for orifice 2 = 0,604; contraction coefficient for orifice 2 = 0,64. Consider both holes
small in relation to the depth of the reservoirs.
