Hi,
First I would like to apologise for my lack of understanding in this area, this is all new for me.
I am designing a water feature (hopefully a working one).
I have a pump that will deliver 31.8 L/min through a 19mm pipe at 1 bar.
If 31.8 litre of water = 31,800 cm³ and if
the volume of pipe to hold 31,800 cm³ would need to be 112.215 metres long.
r .95² x π = 2.83385 cm³
31,800 cm³ ÷ 2.83385 cm³ = 11,221.483 cm
11,221.483 cm ÷ 100 = 112.21483 metres
Q. Does this mean that 31.8 L/min would be equivalent to the speed of 112.21483 m/min.
Q. If I had the pipe from the pump (obviously not 112 metres long) flowing on to a 20 cm diameter water wheel, would the wheel speed be approximately 112.21483 m/min.
Q. Is it the volume of water flow or the pressure that generates the power.
Would a larger pipe providing more volume but less pressure increase the wheel speed or
Would it be a smaller pipe providing less volume but a higher pressure.
Q. Is it possible to calculate the Horse Power or Kilowatts generated by the water flow or pressure on the wheel.
Thank you in advance.
