Explanation Given: Initial volume of water reactor is 1 m 3 , Initial pressure of water reactor is 20 MPa , Initial temperature of water reactor is 360 ° C and final volume is 100 m 3 . Calculation: Properties of water at 20 MPa and 360 ° C are given as follows: u 1 = 1702.8 kJ/kg and v 1 = 0.001823 m 3 /kg . Apply conservation of mass for water filled reactor as follows: m 2 − m 1 = m i − m e m 2 − m 1 = 0 − 0 m 2 = m 1 Mass is calculated as follows: m = V v 1 m = 1 m 3 0.001823 m 3 /kg m = 548.5 kg Final specific volume is calculated as follows: m = V 2 v 2 548.5 kg = 100 m 3 v 2 v 2 = 0.1823 m 3 /kg Thus, this specific volume line crosses the saturated line. Therefore state 2 must be in two phase region as shown below: Neglect the change in kinetic and potential energies. There is no heat transfer and work done for control volume. Apply the energy equation from Eq. 3.5 for water filled reactor as follows: m 2 u 2 - m 1 u 1 = 1 Q 2 - 1 W 2 m ( u 2 - u 1 ) = 0 - 0 u 2 = u 1 Final internal energy of water is calculated as follows: u 1 = u 2 1702.8 kJ/kg = ( u f ) + x ( u f g ) Final quality of water is calculated as follows: v 2 = v f + x v f g x = ( ( 0

If the steem is 100g and the liquid is 12 g. Find the quality of steam?

A frictionless piston-cylinder device encloses 0.226 kg of saturated water-vapour mixture which is initially 10% by mass in liquid. The initial pressure is 1.035 MPa. The fluid is now heated until it all becomes saturated vapour. a. Find the work done during the process. Now, suppose that there is a stop in the cylinder that limits the piston to stop at the top when the volume is 0.0424 m'. b. Find the quality of the mixture when the piston just reached the stop, i.e. when the fluid volume is at 0.0424 m³.

2. 0.3 kg of carbon dioxide is contained in the cylinder with the piston. Initial conditions are 200 kPa, 30 °C. It was compressed to 600 kPa by an isothermal process (a process where the temperature is constant). Find out what has been done during this process.
