Two 10-ft3 adiabatic tanks are connected by a valve. initially, one tank contains water at 450 psia with 10 percent quality, while the second contains water at 15 psia with 75 percent quality. the valve is now opened, allowing the water vapor from the high-pressure tank to move to the low-pressure tank until the pressure in the two becomes equal. determine the final pressure and the final mass in each tank.
