ENGR217 (old spec) Thermo L6 Tutorial 1, Problem 5 official answers

4 kg of saturated water vapour at 300 kPa is heated at constant pressure until the temperature reaches 250 C. Using the steam tables, calculate the work done by the steam during the process.

Formulas you may need

Boundary work at constant pressure: $W = \int p\,dV = p\,(V_2 - V_1)$ (on the formula sheet as $dW = p\,dV$ )
Saturated and superheated steam tables (provided)

volume change =m^3

work done by the steam =kJ
