Calculate average density

[From: ] [author: ] [Date: 11-09-23] [Hit: ]
23kg/m^3, what is the average density of the heated gases in the envelope?-Total weight with full load = (850 + 1800 + 3100) = 5,750N.(1.23 x 2400) = normal air mass of 2,......
A hot-air balloon has a volume of 2400m^3. The balloon fabric (the envelope) weighs 850N. The basket with gear and full propane tanks weighs 1800N. If the balloon can barely lift an additional 3100N of passengers, breakfast, and champagne when the outside air density is 1.23kg/m^3, what is the average density of the heated gases in the envelope?

Total weight with full load = (850 + 1800 + 3100) = 5,750N.
(1.23 x 2400) = normal air mass of 2,952kg., = 28,929.6N.
Difference = (28,929.6 - 5,750) = 23,179.6N.
(23,179.6/28,929.6) x 1.23 = average density of hot air of 0.9855kg/m^3.
