p = miller_p(q,d,pguess,v,sg=1,maxiter=10,threshold=1e-3)
Calculates the pressure drop across a pipeline using the Miller equation suitable for crude oil products.
Volumetric flow rate (
).
Pipe internal diameter (
).
Initial guess for the pressure result in 
.
Liquid viscosity, centipoise.
Liquid specific gravity.
Maximum number of iterations to try to converge.
Iteration completion threshold.
Returns
Pressure drop due to friction (
).
The function could not converge satisfactorily to the given threshold because it exceeded the maximum number of iterations dictated by the maxiter argument.
