A 2000 kg batch of pharmaceutical-grade powder containing 7.5% by
weight water is dried in a drier.
After drying, 95% of the water that enters with the wet powder will
have been removed from the powder.
a. Draw a diagram of the process. Label ALL streams and indicate
stream compositions. Use proper
notations and units.
b. State a basis.
c. Perform an overall material balance and a material balance for
each species.
d. Calculate the final batch composition in wt.%
e. Calculate the final weight of the dried powder (lbm) and the
