Question

Thermodynamic web

Answer 1

As part of a a continuous process, SO2 is expanded through a throttling valve from 100 degrees C, 10 bar to a pressure of 1 bar.
Use the thermodynamic web to derive an equation for the enthalpy change for this process by using T and P as independent variables.
Use \[\text{d}h=c_p\text{ d}T+\left[ -T \left( \frac{\partial v}{\partial T} \right)_T+v \right] \text{ d}P\]
as starting point

Answer 2

I made a typo:
\[\text{d}h=c_p\text{ d}T+\left[ -T \left( \frac{\partial v}{\partial T} \right)_P+v \right] \text{ d}P\]
