Does temperature have a big influence on the volume of oil or pressure has a big effect on the volum

Temperature. As the temperature increases, the spacing between oil molecules increases.

As the pressure increases, the interval between oil molecules decreases.

But stones are liquids, and the space for the molecular spacing to become larger is much larger than the space to become smaller.

So the temperature has a big impact.

Temperature. The volume and temperature of liquids and solids are more affected than pressure.

At a given temperature, the mass of a substance contained in a unit volume is called the density of that substance, expressed in kg m or cm. Since the volume of petroleum products varies with temperature, and its density also changes with temperature, the density meter readings observed at a certain temperature are called the apparent density of the substance. Therefore, it is important to indicate the temperature t when determining the density of petroleum products.

The density of petroleum and petroleum products at a standard temperature (20 and 20 is called standard density. The apparent density values measured at other temperatures should be converted to standard densities and the test results should be reported.

6. Determination principle: The densitometer method is based on Archimedes' law. Put the sample at temperature, pour it into a density measuring cylinder with about the same temperature, put a suitable density meter into the sample that has been adjusted temperature, when the density meter sinks into the liquid petroleum product, a small part of the liquid is discharged, and the density meter is affected by the buoyancy of the weight of the liquid it discharges.

According to Archimedes' law, when the weight of the liquid discharged by the density meter is equal to the weight of the density meter itself, that is, when the buoyancy force experienced by the density meter is equal to the gravitational force acting on it, the density meter floats in the petroleum product and is in equilibrium. When the temperature reaches equilibrium, the density meter reading and the specimen temperature are read. The observed density meter readings are converted to standard densities using a petroleum meter.

How to convert the volume of ** at different temperatures.

First of all, you should have a standard volume of a certain quality** at different temperatures.

Then according to the same quality, the volume is calculated according to the above table.

The relationship between the pressure and the boiling point at different densities.

**The density is generally GB 1884 and GB1885

The conversion and calculation can be converted to 20 degrees Celsius using the density of the measured temperature of 15 degrees, 70 degrees, 60 degrees, etc., which also includes pressure correction.

My operating pressure is about the same, and I am completely in a liquid state. Water and ** are both liquids, which can be regarded as incompressible fluids, that is, the density of the two is only related to temperature, and the pressure has little effect and can be ignored.

How much natural gas does it take to heat one ton** and raise the temperature one degree.
