Q=4.03 x 10^-5 x D^2.65 x H^0.54
I would like to use this formula to size a water pipe (D). I have Q from flow requirements. How do I determine H? The pump is rated 50 m head. Distance of flow circa 1000 m.
The system is already in place. We just want to buy a standby motor, unfortunately the company that supplied the current motor is no longer in operation and the namplate is ineligible. We need a point of reference when getting in touch with suppliers.
Tnx.
How can I calculate the power requirement (winch, motor size) given the safe working load and the tare mass of a man cage? Thought of using F=m.a and Power= F.V. Am I on the right track? Any help will be appreciate.
Regards.
Kristian
