Question

A piston-cylinder device (closed system) contains H20 at Pabs = 0.01 MPa (absolute scale) and50°C. The density of H20 is 0.067263 kg/m³3. A. You are interested in studying the H20 in the piston-cylinder device as a closed system.Draw a schematic of your device and the boundary that defines your system. B. Determine the specific volume of the H20 in m3/kg. C. If the mass of the H20 is 2 kg, then what is the volume of the H20 in m³? Use the specific volume (NOT density) for this calculation. D. What is the vacuum pressure of H20 if an atmospheric pressure is Patm = 101 kPa?
