A Commercial Popcorn Popping Popcorn Popper:
We are constructing a 1L popcorn popper to be operated in steady flow. First tests
in this unit show that 1 L/min of raw corn feed stream products 28 L/min of mixed
exit stream. Independent tests show that when raw corn pops its volume goes from
1 to 31. With this information determine what fraction of raw corn is popped in the
unit.
