Determine the total length of the 1/2" tube that is required to provide the DHW. Determine the mean diameters of the three coils, and the length of tube in each coil.
At the point where the spring is compressed a distance d (before the maximum compression, as the elevator is still dropping), find an expression for the speed.
Why does turbulent flow distribution adhere more closely to the idealization of one dimensional flow than laminar flow? What significance does the velocity distribution have for mass flow rate measurement in pipes?
