The highest reservoir in a three-reservoir branching system is inaccessible after a mountain storm. Determine the surface elevation of this reservoir given the following water surface elevation and pipe data (lengths and diameters):

All of the pipes are rough concrete (e = 0. 6 mm), so complete turbulence is assumed. The actual elevation of the junction (J) is 4,072, and the pressure at the junction is 127 kPa.
