Saturated Water in A Piston- cylinder

A mechanical engineering student gets an internship in a power plant. His first task is to design a piston-cylinder device which is used to vaporize the saturated water to saturated vapor under a given pressure. The volume of the device and how much heat needed for the vaporization process are the first thing he has to figure out.

What is known:

• The mass of water m = 10.0 kg
• Operation pressure P = 100.0 kPa
  

• What is the volume change from liquid water to vapor
• How much heat is added for the vaporization process

• Latent heat of vaporization (L_V) of water under 100 kPa is 2257.0 kJ/kg.
• Specific volume (Will be introduced in next section) of saturated water (v_f) under 100 kPa is 0.001 m³/kg.
• Specific volume of saturated vapor (v_g) under 100 kPa is 1.673 m³/kg.
