Determine whether methanol is in a liquid state or a saturated state under these conditions Do you need the calculation process?

Is the pipeline medium a methanol mixture? What is a mixture of methanol with? ? If it is pure methanol, one only needs to look up the saturated vapor pressure of methanol. Actually, there’s no need to go through such trouble; the boiling point of methanol is 64.7°C at 0.1 MPa. Since the current pressure is 0.19 MPa and the temperature is 45°C, it is definitely in liquid form.
Based on the composition, if the concentration of any component reaches or exceeds its saturated vapor pressure at that temperature, a mixed phase of liquid and gas exists.
