Water is contained in two closed tanks (A and B) which are connected by a pipe at 1 m above the ground level. The tank A is pressurized at 1.5 atm pressure with nitrogen gas above the water level while tank B is pressurized 4 atm with nitrogen gas above it. For both tanks, it can be assumed that nitrogen behaves as an ideal gas under these conditions. Initially, the water level in tank A is 3 m above the ground whereas tank B is above 2 m above ground. Each tank is identical and made from stainless steel with a total height of 4 m and the base area of 1 m2 . Which direction does the water flow and what is the equilibrium height in each tank?
