Calculating the Dimensions of a Hot Air Balloon
The formulas necessary to calculate the balloon’s dimensions were taken from the reference books Brockhaus Physics Lexicon and the handbook Syllabus for Gas Engineers.
I have now put these formulas in an MSExcel spreadsheet which enable a balloon to be correctly calculated. The formulas are specifically tailored for a balloon with the shape indicated in brown in the bottom righthand corner of the picture. This is in fact the shape that all of our balloons had.
The “Balloon Calculator” program can be downloaded as a zipfile by clicking on the picture below.
