To begin your activity, open this tracker experiment: Snowboard Jump Energy. Watch the movie by clicking on the play button. (The other video controls allow you to “rewind” the video or step forward or backward one frame at a time.) Observe the video and answer the following questions.

Part A
What can you say about the snowboarder’s kinetic energy as he moves?

Part B
Similarly, what can you say about the potential energy of the snowboarder?

Part C
Based on your observations, what can you say about your prediction in Parts A and B above concerning the potential and kinetic energy?

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
