8) A pump, submerged at the bottom of a well that is 35m deep,is used to pump water uphill to a house that is 50m above the topof the well, as shown above. The density of the water is 1000kg/m3. All pressures are gauge pressures. *top of well pipe tohouse angle = 30 degrees*
Residents of the house use 0.35 m3 of water per day. The dayâspumping is completed in 2 hours during the day.
a) Calculate the minimum work required to pump the water perday.
b) Calculate the minimum power rating of the pump.
The average pressure the pump produces is 9.2x105 N/m2. Within thewell the water flows at 0.50 m/s and the pipe has a diameter of 3.0cm. At the house the pipe diameter is 1.25 cm.
c) ( Calculate the flow velocity when a faucet in the house isopen.
d) Calculate the pressure in the pipe near the faucet at thehouse.
