Angle of Trajectory:
Before we constructed our cannon we came to the conclusion that the angle of our cannon should be at 45°. We decided on the 45° because it seemed like the logical angle to max out our height and distance.

The Gas Law- Boyle’s Law: As for the design of our cannon we decide to take in Boyle’s Law that states that volume and pressure are inversely proportional. So, if the volume on our cannon is decreased the pressure will increase or vice versa. Providing the cannon with a small combustion chamber was ideal to maxing out our maximum distance. We had to be careful because with a chamber that is too small the oxygen inside will become the limiting reagent instead being excess. Ethanol had to be the limiting reagent in order to have a decent reaction.
Steps Toward A Balanced Equation:
The formula for combustion reactions is CxHx + O2 → CO2 + H2O . The chemical formula of ethanol is C2H5OH. As shown to the right, the chemical equation for this reaction is C2H5OH + O2 → CO2 + H2O. The next step will be to balance this equation.
A Completed Balanced Equation:
C2H5OH + O2 → 2CO2 + 3H2O
C2H5OH + O2 → 2CO2 + 3H2O
I like how on this topic, you really explained the topics without going into TOO much deatil. This is very concise and looks good! I think it looks better when you have white behind the text as opposed to actual WHITE text.
ReplyDeleteI like how you explained what you did and why you chose your designs, but although a 45 degree angle would be the best angle in a vacuum we aren't firing them in a vacuum so the angle should be a bit lower to counter resistance.
ReplyDeleteIs Khyer on your team? Because if not, he should keep his designs to himself (not being rude at all) but if something works for his group, he might not want to share it... just saying. Great job and good LUCK with the firing(when we actually DO fire them).
