An insulated tank containing 0.4 m3 of saturated water vapor at 500 kPa is connected to an initially evacuated, insulated piston-cylinder device. The mass of the piston is such that a pressure of 150 kPa is required to raise it. Now the valve is opened slightly, and part of the steam flows to the cylinder, raising the piston. This process continues until the pressure in the tank drops to 150 kPa. Assuming the steam that remains in the tank to have undergone a reversible adiabatic process, determine the final temperature
(a) in the rigid tank and
(b) in the cylinder.
At a certain point, A, in its motion, its velocity angle is 19° above the horizontal. At another point, B, later in its motion, its velocity angle is 39° below the horizontal. Illustrate what is the horizontal distance from point A to point B?
