[QUOTE="Chris02NeonSXT, post: 1186163, member: 544477"] Here's the question: A helium filled blimp is capapble of providing a gross lifting capacity of 1100 kg. Assume atmospheric pressure is 101 kPa, ambient temperature is 15*C, and that the blimp has the shape of a prolate ellipsoid. Its volume is given by the equation: V=4/3pi*a*b^2, where "b" = 1/2 the diameter and "a" is 1/2 the length, and a=4b. I need to find the length and diameter. Any ideas how to even start this problem? Are there any thermo web sites you guys use? [/QUOTE]
