Question 1 (Pumps, pumping and water clarification)
1.1 List five different ways in which the pumping of fluids can be accomplished.
1.2 In a winze inclined at 30° to the horizontal, 36 kilolitres per hour must be pumped
through a column of 300 m from the bottom to the top of the winze by means of
a centrifugal pump.
Assume the following:
• Velocity is not to exceed 1,5 m/s
• Coefficient of pipe friction = 0,01
• Pump and drive efficiency = 78%
• Motor efficiency = 90%
Determine:
a) the size of column required
b)
the power of the electric motor to drive the pump
