Two reservoirs 1500 m apart have a water surface elevation difference of 18 m. A cast iron pipe with >= 0.26 mm connects the two reservoirs. The entrance is square-edged. The pipe diameter is 0.5 m. Water at 20°C flows under the action of gravity between the 2 reservoirs. A gate valve (Kv = 10 fully open) controls the flow between reservoirs. Determine the discharge when the gate valve is fully open.

Two reservoirs 1500 m apart have a water surface elevation difference of 18 m. A cast iron pipe with >=
0.26 mm connects the two reservoirs. The entrance is square-edged. The pipe diameter is 0.5 m. Water
at 20°C flows under the action of gravity between the 2 reservoirs. A gate valve (Kv = 10 fully open)
controls the flow between reservoirs. Determine the discharge when the gate valve is fully open.
