Please show all steps and formulas used to solve for the 3 parts.

3. Variations of this problem to discuss and solve: Every number in red could be changed You have a contract to transport exactly 250,000bbl/ day of oil to a refinery at an average pipeline temperature of 60F and 900 psia. The oil viscosity required for pipeline transportation is 300cp. You have unlimited quantities of an 11API heavy oil ("HO") and a steady supply of 10,000bbl/ day of a 28 API lighter oil ("LO") that you MUST use. However, even after mixing these two oils the viscosity is too high for pipeline transportation. One option is to dilute it even further with a46API solvent ("S1"). Provide an estimate of the daily volume of solvent (S1) that you need to purchase such that the oil reaches target viscosity of 300cp. The following items guide you on what is required. Show your work very clearly and write down the final answers (all the ories I request) in the boxes provided. API of final oil mixture including solvent
