Day 6 Otto Cycle

We first started with a ThermoElectric Cooler. In order for the cooler to work it needs to water reservoirs of different temperatures.

Another picture of Cooler, top view.
Top View of Cooler, it has legs in two different temperatures waters.
A Video of the Cooler working.
Another video of it being powered electricity.
Cooler being powered by Electricity.
You can tell it works if the top is spinning. It is being powered by the different temperatures of water.















Picture of Incredible Mass lifter. Uses trap air to lift things. In order to control the lifting you heat up syringe.


Pictures of the system and trying to find the work done. Data from Logger Pro.
Area enclosed is the work done. 25.98kPA.

The change of volume, pressure, and Temperature of the closed system.

Us trying to find the work done using data from Logger Pro.
We set up a PV-Diagram. trying to find work.

Algebra work trying to find Cp, CP turns out to be 5/2 R.

 Adiabatic process trying to find work.
Gas Expands so postive work. W = 1246J.

 Using the properties if adiabatic and finding the difference in monotamic gas and diatomic gas.
 We then had to work out the Carnot Engine Cycle. We draw the PV-Diagram. and used the formulas and properties for each section.
White board work. It is messy but we got efficiency to be 33%.
Summary:
We started the day with a ThermoEletric Cooler. Showed how different resaviors of water can be used to cause work.
We then tried to find work done by a closed system of the incrediable mass lilfter, from data of logger pro.
Then we did some algebra work to find Cp, Cp is 5/R. It is useful for constant pressure process.
Learned different coefficient for monoatmoic and diatomic gases.
Lastly we did a complete Carnot Engine Cycle problem. The end efficiency of the Carnot is 33%.
