You are helping to design a new hot air balloon for an upcoming regatta. Assuming that the temperature to which the air inside the balloon can be safely heated is 85 ˚C, what is the minimum volume require for the balloon if it is to lift a total weight (balloon plus passengers) for 250 kg. Take the outside air temperature to be 15 ˚C, the air pressure to be 1.00 bar, and make a reasonable assumption as to the composition of air (i.e., as mole %, 79% N2 and 21% O2). You can assume ideal gas behaviour.

    A hot air balloon has a volume of 2000 m3 when fully inflated and the air inside the balloon is at atmospheric pressure (101,000 Pa). What is the mass of hot air inside the balloon if its temperature is 120°C? (Assume a molecular weight of 28.8 g/mole for air, which is about 80% N2 and 20% O2.)

    5. A very large hot air balloon and its accompanying structure (i.e. the basket, rigging, equipment, etc) have a mass of 400 kg. The air inside the balloon must be heated to a temperature of 200 OC for the balloon to lift off the ground when the outside air temperature is 16.0OC. To what temperature must the air be heated if the balloon is to lift off with three 80.0-kg people aboard? Note: Problem 5 requires three pictures of the...

    The mass of a hot-air balloon and its cargo (not including the air inside) is 200 kg. The air outside is at 10.0°C and 101 kPa. The volume of the balloon is475 m3. To what temperature must the air in the balloon be heated before the balloon will liftoff? (Air density at 10.0°C is 1.25 kg/m3.) 1 K

    Constants Part C Hot air balloons float in the air because of the difference in density between cold and hot air. Consider a balloon in which the mass of the pilot basket together with the mass of the balloon fabric and other equipment is mb. The volume of the hot air inside the balloon is Vi and the volume of the basket, fabric, and other equipment is V2. The absolute temperature of the cold air outside the balloon is T...

    Answer all parts including a picture showing all variables please! Thank you 1. While I was in the Serengeti I saw people watching wildlife froma hot air balloon. Seemed great. Imagine this: You fly down there and on a wonderful day at 20°C, you are supposed to take off You are skeptical about the hot air balloon carrying you, your two friends, the operator, the operator's dog, the weight of the balloon itself and all the sandwiches and beverages. From...

    3) Consider the hot air balloon problem described in Lecture 1, pp. 22-24. That problem assumed an outside air temperature of T- 300 K (27°C or 80.6°F), arn atmospheric pressure of 1.013 x 10 Pa (at sea level), and a spherical balloon shape. We would like to perform the same calculation but assuming atmospheric pressure in Albuquerque, NM, where the altitude is 1620 m wikipedia.org/wiki/Albuquerque_International_Balloon Fiesta) (a) First, we need to estimate the ambient pressure at an altitude of 1620...

    -Rome can get pretty hot in the mid-summer! Most of the air conditioning units in the Tiber campus use the working fluid R-134a (1,1,1,2-tetrafluoroethane), which is replaces the less environmentally-friendly R-12 of years ago. a) Illustrate the following air conditioning cycle, indicating material, heat, and work flows, as well as given/known temperatures and pressures: R-134a is pressurized to 10.2 bar in an adiabatic, reversible compressor. This high-pressure, hot refrigerant is condensed outside of the building using ambient air to a...

    part a. The air in an inflated balloon (defined as the system) is warmed over a toaster and absorbs 110 J of heat. As it expands, it does 79 kJ of work. What is the change in internal energy for the system? Express the energy in kilojoules to two significant figures. part b. When fuel is burned in a cylinder equipped with a piston, the volume expands from 0.235 L to 1.350 L against an external pressure of 1.02 atm...
