    6. A pump, submerged at the bottom of a well that is 35m deep, is used to pump water uphill to house that is 50m above the top of the well, as shown above. The density of water is 1,000 kg/m3. All pressures are gauge pressures. Neglect the effects of friction, turbulence, and viscosity.

    a. Residents of the house use 0.35 m3 of water per day. The day's pumping is completed in 2 hours during the day.
    i. Calculate the minimum work required to pump the water used per day.
    ii. Calculate the minimum power rating of the pump.
