Mathematical modeling aids in technological design by simulating how. 1. A solution should be designed
2. A proposed system might behave
3. Physical models should be built
4. Designs should be used

What precautions should you take to prevent injuries when dealing with heavy loads?

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
