Transcribed Image Text:4. A pump pushes 1000 m³ of liquid water at 15°C up to a reservoir at 200 m higher elevation.
The whole process takes 6 hours. How much work does that require? What is the power of the
motor that is required to accomplish this? Provide your answers in kW and hp (horsepower)
5. A hydraulic piston in a tractor should push with a force of 2000 N over a distance of 0.25 m.
The piston cross sectional area is 10 cm² and we neglect the presence of the atmosphere in this
calculation. Find (a) the pressure of the hydraulic fluid, (b) the volume change that occurred in
the piston cylinder and (c) the work transferred.
