P-v-t relationship/saturated vapor pressure of dimethyl ether (dme) as an alternative for liquefied petroleum gas and determination of 8 constants in the benedict-webb-rubin (bwr) equation of state

The P-V-T relationship was measured for ethane for 3 isotherms, propane for 10 isotherms, and dimethyl ether (DME) for 10 isotherms using a constant volume method in the temperature range from 350.00 to 450.00 K, and pressure up to 8.341 MPa. Saturated vapor pressure was also measured for propane, b...
