Dahm/Visco Fundamentals of Chemical Engineering Thermodynamics Chapter 1
REQUIRES ACCESS TO THE STEAM TABLES
1. 100 kg of water is contained in a piston-cylinder device. Initially, it is saturated liquid water
at P=10 bar. It is heated at constant pressure until it is superheated steam at P=10 bar and
T=250 °C.
A) Determine the change in internal energy (U) of the water, in kJ.
B) Determine the amount of work (WEC) done on, or by, the water in this process.
SOLUTION:
Specific internal energy and specific volume are both available in the steam tables.
A)
