Class 19  Thursday, 10/23/2014
Warm-Up: 

The last thing you have to do, regarding your hot air balloon, is to determine the temperature reached by the hot air inside.  How will you do this?

Today:   

  • Mr. Stapleton will be gone next class.
  • Once your balloon is complete...
    1. Measure your balloon's volume (shop vacu apparatus flow rate is 0.201m3/second.  Let it get up to speed before covering the hole with your balloon.)
    2. Measure the non-air mass of your balloon.  Include the Sterno mass.
    3. Just prior to flight, record the room temperature in Fahrenheit and the air pressure in inHg.
    4. Fly your balloon and measure lift.
    5. Enter your final data into the EPS Class Balloon Data Sheet
      • The sheet is inside the Hot Air Balloons folder in your Shared With Me Google Drive.
      • One of the columns requires you to calculate the air temperature inside your balloon.  In order to do this, you will need to use the temperature and density calculator that was provided in the last homework assignment.

Homework:  Hot air balloon spreadsheet quiz next class.  Try this interactive practice Quiz spreadsheet.  I'm calling it interactive because it tells you if you're getting the answers right or wrong.  Here's an 8:34 video showing you how to complete the spreadsheet. If you have mastered the content on this quiz, you will do well on Monday's quiz.  Expect the quiz to be organized differently, but the questions will essentially be the same.
Class 18  Tuesday, 10/21/2014

    • Enter your final data into the EPS Class Balloon Data Sheet
      • The sheet is inside the Hot Air Balloons folder in your Shared With Me Google Drive.
      • One of the columns requires you to calculate the air temperature inside your balloon.  In order to do this, you will need to use the temperature and density calculator that was provided in the last homework assignment.

    • Measure volume
    • Measure empty mass

3.  A jet of air can be used to levitate a ping-pong ball.  The most curious thing about this is that the position of the ball in the jet of air remains fairly stable.  The ball is attracted to the jet of air.  What does this tell you about the pressure of fast-flowing air?

Today: 

  • Get your plastic sheet and begin laying out your balloon construction.  Measure your sheet.  If necessary, adjust your model scale to reflect the actual amount of plastic that you have.
