Two reservoirs are connected by a pipe whose total length is 36 m as shown in Figure 2. From the upper reservoir, the pipe is 250 mm in diameter for a length of 12 m and the remaining 24 m are 125 mm in diameter. The entrance of the pipe is a square-edge inlet and the change of section is sudden. The difference in levels of the water in the two reservoirs is 10 m. The friction coefficient, f, is 0.06 for both pipes and the loss coefficient, K, for sudden contraction is 0.3. Determine the flow rate in the system. Type of losses:

for sudden contraction is 0.3. Determine the flow rate in the system. Type of losses:
Entrance loss (square edge inlet)
Friction loss due to pipe 1 (f=0.06)
Sudden contraction (K=0.3)
Friction loss due to pipe 2 (f=0.06)
Exit loss (K=1.0)
