Discharge Between Two Reservoirs

Pipeline connecting two reservoirs. Pool elevations are Z1 and Z2.
Pipeline length is L, diameter is D, sand roughness height is ks.
Pipeline can be analyzed with entrance and exit loss coefficients (Ki and Ke).
Pipline can be analyzed with 2 fitting (Kf) loss coefficients.
A three point pump performance curve is supplied -- shutoff head is one point.
Calculator solves for flow rate in the pipeline.

Uses Jain equation to make initial flow estimate,then Newton's method to refine the estimate.
