Two cast-iron pipes connect two reservoirs (e = 0.26 mm). Pipe 1 is 400 m and pipe 2 is 300 m.
The diameter of pipe 1 is 0.5 m and pipe 2 is 0.3 m. The discharge of 15 °C water from the upper reservoir A to the lower reservoir B is 0.6 cms.
A) Using a straightedge, sketch and label the hydraulic and energy grade lines. Label the dimension describing the difference in elevation between the reservoirs.
B) Find the elevation of the surface of reservoir B. Assume a sudden contraction at the junction and square-edged entrance.
