Three hundred gallons of a mixture containing 75% by weight of ethanol and 25% of water (specific gravity [ge] of the mixture = 0.877) and a certain amount of a mixture of 40% ethanol and the rest of the water (ge = 0.952) are combined to produce a mixture containing 60% ethanol weight. based on this information, it is requested:
1. draw the process flow diagram, indicating each of its streams and compositions (known and unknown).
2. determine the necessary volume of the mixture containing 40% ethanol.
