This program was made to perform biphase flow pressure drop calculation, liquid hold up and flow type. The pressure drop calculation uses the following correlation:  VDI - Horizontal and Vertical case, Duckler - No Slip and Constant Slip case, Beggs and Brill, Lockhart Martinelli. For liquid hold up the calculations were made using: Lockhart Martinelli correlation, Hughmark, Eaton, Beggs and Brill. Korf note - To compare Dukler results to Korf, set pipe roughness to 0 in Korf.
