With the solution methode, please

Given the following reservoir/fluid data: Sw= 0.21 Krw = 0.13 Kro - 0.83 Sw -0.43 Krw = 0.32 Kro = 0.56 viscosity of oil = 3 cp viscosity of water = 1.0 cp If the relationship between Kro/Krw and Sw can be approximated by 1. Estimate the parameter (b). 2. Estimate the parameter (a). 3. Calculate the Kro/Krw at the following water saturation points: Sw = 0.47 Kro/Krw = Sw = 0.57 Kro/krw = 4. Estimate the fractional flow of water (fw) at the following water saturation points: Sw = 0.47 fw = Sw = 0.57 fw
