A person is about to take off in an air balloon, full of helium, can be considered as a sphere with a radius of 7.5 m. The basket and balloon material have a combined mass of 314 kg. The balloon is kept from moving up by a certain amount of ballast, in the form of sandbags, which provides its own weight. The person has a mass of 125 kg. Helium has a density of 0.18 kg/m3, while air has a...

A 12-cm tall, 6-cm outer diameter cylindrical ceramic mug filled with tea is boiling in a microwave oven. Assume latent heat of evaporation as 2260 kJ/kg. The convection heat transfer coefficient is h=20 W/(m 2 K) and the air in the microwave is at 20 °C. The mug’s wall thickness is 6 mm and the ceramic thermal conductivity is 30 W/(mK). Neglect heat transfer from the bottom of the mug and calculate the rate (in g/s) at which the tea...
