Correlations

Pressure, temperature, and friction factor correlations. Not used directly but passed as model arguments.

Pressure drop correlations
- [Beggs and Brill](@ref BeggsAndBrill), with Payne correction
- [Hagedorn and Brown](@ref HagedornAndBrown), with Griffith and Wallis bubble flow correction
Temperature correlations & methods
- [Linear temperature profile](@ref linear_wellboretemp)
- [Shiu temperature profile](@ref Shiu_wellboretemp): Ramey temperature correlation with Shiu relaxation factor
- [Ramey temp](@ref Ramey_temp): single-point Ramey temperature correlation
- [Shiu relaxation factor](@ref Shiu_Beggs_relaxationfactor)
Friction factor correlations
- [Serghide friction factor](@ref SerghideFrictionFactor)(preferred)
- [Chen friction factor](@ref ChenFrictionFactor)
