Nellie-B has a weight of 1,250 lbs and its envelope has a volume of 115,000 ft^3.
Let's say that the air temperature in Albuquerque is 10 C. The butane burners in the balloon heat the air inside the envelope to 100 C.
Albuquerque is at an elevation of 5,000 ft and the air pressure there is only 12.1 psi. Because of Albuquerque's high elevation, the air density there is only 1.027 kg/m^3.
- What gas is considered lifting gas for the for a hot air balloon?
- Write down the equation you would use to calculate the total lift of this hot-air balloon
- In the equation you wrote above, circle the quantities (variables) that are already given. Show, with a question mark, the variables that are not given.
