A rigid tank A is connected to a spherical and elastic balloon
B. Each contains air at an ambient temperature of 25 ° C. The
volume of tank A is 0.1 m3 and the initial absolute
pressure is
300 kPa. The initial diameter of the balloon is 0.5 m and the
internal absolute pressure is 100 kPa. The tap connecting A and B
is opened and left open. It can be assumed that the pressure inside
the balloon is directly proportional to the diameter of the balloon
and that the final air temperature therein is uniform at 25 ° C.
Determine the final pressure in the system and the final volume of
the balloon.
ans: Pfinal = 137 kPa Vfinal= 0,167 m3
