Problem 81HP
Two piston/cylinder arrangements, A and B, have their gas chambers connected by a pipe, as shown in Fig. P1.81. The cross-sectional areas are AA = 75 cm2 and AB = 25 cm2, with the piston mass in A being mA = 25 kg. Assume an outside pressure of 100 kPa and standard gravitation. Find the mass mB so that none of the pistons have to rest on the bottom.
