A pump station needs to raise 200,000 meters cubed of water to a resevoir 420 meters in height above the pump station. The water needs to be pumped in five hours during the night.

[LIST=1][*]What would be the flow rate required? [B](1)[/B][/LIST]
The pipe used, after taking into account bends and fittings has an equivalent length of 480m and has a diameter of 2.2m. The friction factor for this pipe is 0.0650.

[LIST=1][*]What are the head losses? [B](2)[/B][*]What is the hydrualic power needed? [B](2)[/B][*]What would be the efficiency of the pipe? In other words what percentage of the hydraulic power is losses? [B](1)[/B][*]What is the Mechanical pwer required? [B](1)[/B][/LIST]
f. What is the Electrical power erquired?

Is this homework?
