If you know that
x (0)=10kg
y (0)=8kg
Molly sets the storage cylinder pump settings as
follows:
Molly
The salt water is pumped from storage cylinder 1
to storage cylinder 2 at 10L per minute and it is
pumped from storage cylinder 2 to storage
cylinder 1 at 10 L per minute.
Molly knows that storage cylinder 1 has 50 liters of
salt water in it and that storage cylinder 2 has 25
liters of salt water in it. Assuming that the salt and
water is mix perfectly in each tank and that x is the
amount of salt in kg in storage cylinder 1 after time
(t) minutes has passed and y is the amount of salt in
kg in storage cylinder 2 after time (t) minutes has
passed;
Help Molly determine the quantity of salt in each
storage cylinder after t minutes.
x (t) =
y(t) =
Molly wants to know, at time reaches infinity how much
salt would be in each storage cylinder.
Storage cylinder 1 should contain
salt
Storage cylinder 2 should contain
salt
