ASTM D97 is a manual method used to determine the pour point of any petroleum-based oil. In this method, the oil sample is placed into a vessel and pre-heated, and this is followed by a cooling stage so that the oil is at a temperature of 9 °C (48.2 °F) above its expected pour point. This enables the formation of paraffin wax … WebApr 3, 2024 · The absolute viscosity of many fluids relatively doesn't change with the pressure but very sensitive to temperature. For isothermal flow, the viscosity can be considered constant in many cases.
