Estimate the Molar Volume of Isobutane at

Example 19 Estimate the molar volume of isobutane at 155°C and 8.6 MPa pressure. 

The work of the pump is given by Eq. (7.24), and for this we need an estimate of the molar volume of isobutane as a saturated liquid at 450 kPa. This is given by Eq. (3.72). The saturation temperature at 450 kPa is given by the Antoine equation solved for t degC ...
