3. Steam Source (based on former midterm problem) A piston-cylinder device with a cross-sectional area of 0.021 m² is being used as a source of gaseous water (steam). A spray of liquid water droplets is injected into the cylinder at a flow rate of 0.37 g/s. The liquid water evaporates nearly instantaneously after being injected. The steam in the cylinder is maintained at a constant pressure of 19.0 psia by a force (F) applied to the piston, while a heating system maintains the temperature inside the cylinder at a constant temperature of 524 K. Steam leaves the cylinder at a velocity of 69.0 m/s from a hole in its side with a cross-sectional area of 8.33 mm². Assuming the steam leaving the cylinder has the same properties as the steam inside, determine if the piston will move, and if so, in which direction. Piston Liquid F
