1. Define the problem: state what needs to be achieved. 2. Research: describe the information you used or Tooked up to come up with ideas.
3. Generate Ideas: list 3 different ideas that could be used for your new and improved salt and
pepper shaker
4. Develop a design: sketch your final idea on paper.
5. Test: show your design to someone else and explain how it works. Ask for feedback on your idea.
6. Evaluate: Based on feedback, describe how you would change your design.

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
