Question 1
This question requires the use of the Thermodynamic Property Tables supplied as
additional material.
In addition, for steam, the specific ideal gas constant = 461.5 J/kg K
A closed system is comprised of 10 kg of pure water substance initially at a temperature of
400 °C and a pressure of 8.5 MPa (state 1).
(a) For state 1, show that the system is in the superheated vapour phase.
(b) Evaluate the specific volume of the steam in state 1 using the thermodynamic property
tables supplied and compare it to the value obtained assuming the steam behaves as
an ideal gas.
Which value would you have most confidence in (give reasons for your choice).
The system now undergoes an isentropic (constant entropy) adiabatic process during
which its pressure drops to 100 kPa (state 2).
(c) For state 2 show that the system is now in the two-phase region.
(d) Find the work done by the system on its surroundings during the process.
