culstor/e8mpu31 (a) It is known that density p of air decreases with height y aswhere po 1.25 kg m is the density at sea level, and y, is a constant. This densityvariation is called the law of atmosphere. Obtain this law assuming that thetemperature of atmosphere remains a constant (isothermal conditions). Also assumethat the value of g remains constant.(b) A large He balloon of valume 1425 m3 is used to lift a payload of 400 kg. Assumethat the balloon maintains constant radius as it rises. How high does it rise?[Take yo = 8000 m and pHe = 0.18 kg m*). |
