2. Water is pumped from a lower reservoir using a 75 kW pump. If the height of water at the higher reservoir is 120m. And the flow rate of the pump is 0.03 m^3/s, what are the head losses of the system? 120m 75kW Pump

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.

Water is flowing in a 3 m wide rectangular channel. A hydraulic jump occurs and the flow upstream is 360 mm deep while the flow downstream from the jump is 1300 mm deep. A) Find the discharge flowing in the channel. B) Find the energy absorbed by the jump in kW. Please answer correctly

For water supply of a town, water is pumped from a river 4km away into a reservoir. The maximum level difference of river and reservoir is 20m. Town population is 50,000 and per capita water demand is 120 lpcd. If the pumps operate for a total of 8hrs and pump efficiency is 60%, calculate pump B.H.P Assume friction factor as 0.0075 and pipe velocity as 2m/s and maximum daily demand as 1.6 times avg. daily demand.
