ECOR 2606 Assignment #4
1/.
Two skydivers jump out of a stationary balloon. The first skydiver has a drag coefficient of
0.3 kg/m and a mass of 60kg. The second skydiver has a drag coefficient of 0.2 kg/m and a mass
of 50 kg. If the second jumper jumps 3 seconds after the first jumper, how long will it take him
to catch up with the first jumper?
Initially the distance between the jumpers will increase.
What
will the maximum separation be and at what time will it occur?
Express all times in seconds
after the second jumper's departure from the balloon.
All necessary formulas can be found in the notes and the text. Submit an mfile (to be called
skydivers.m) that determines and outputs the required values. See the note at the end of this
assignment.
2/. This question is problem 8.5 from the text. A process involves five reactors, two input flows,
and two output flows.
The diagram shows the flow paths and volume of each flow.
Assume that
the flows are in l/s. (it doesn't really matter what the units are but having units makes the
