double pressure_drop(double diameter, double flow)

As a fluid moves down a pipe, friction with the pipe generates heat and sound and leads a loss of energy within the fluid. Due to Bernoulli law, if there is a loss of energy yet constant flow, then there must be a reduction in pressure.

This function computes this pressure drop for a 100ft length of pipe. To compute the pressure drop for a shorter or longer pipe length, scale the number as appropriate.
