Three hundred gallons a minute of a mixture containing 75.0 mass% ethanol and 25 mass% water (mixture density - 0.877 lbm/gal) and a quantity of a 40.0 mass% ethanol-60% water mixture (mixture density = 0.952 tbm/gal) are blended to produce a mixture containing 60.0 mass% ethanol. Determine the required mass and volumetric flow rate of the 40 mass% mixture inlbm/hr and gal/hr, respectively and the final resulting mass flow rate of the exiting stream in lbm/hr. What variables are in the word problem? Which are known and which are unknown? What does picture look like? What equations do we need in which order? What are answers? Document your work at each step
