Question

In a small hydroelectric plant, a simple surge tank of 3.5 m diameter is positioned 150 m downstream of reservoir. the supply tunnel is 1.2 m in diameter and the friction factor is estimated as 0.01. The initial flow to the turbines is 2.25m3/sec. Calculate the maximum up level in the surge tank relative to the initial steady-state level. (choose the time step every 20 second and surge friction lose equal to (1)).
