Quite often accountants should come up against such situation when in primary documents from the supplier the cost of gasoline is specified per one liter, and delivery of fuel has to happen in kilograms. Then there is a need of the transfer from units of volume to units of mass.
It is required to you
- - calculator;
- - handle;
- - tables of physical and chemical properties of oil products;
- - paper.
Instruction
1. To make a transfer of liter of gasoline to kilogram, calculate the specific weight of fuel, that is its density. This size has the special importance for storage of fuel in tanks. Density of gasoline can be found, having divided its weight into volume. However, density of all oil products – size relative as very strongly depends on air temperature changes.
2. Dealing with dimensionless size, divide gasoline volume at a temperature which was recorded at the time of definition, on the mass of water at a temperature of 4 wasps taken in just the same volume since at this temperature it is precisely known that the mass of water is equal to one kilogram. The turned-out value is relative density.
3. At temperature increase the volume of gasoline increases. To determine its density, subtract from the increased temperature initial and increase the received value by coefficient of volume expansion of gasoline. Find value of coefficient in the table of physical and chemical properties of oil products. To the required work add unit. Increase the turned-out sum by the initial volume of gasoline. Thus, you learn how gasoline volume at temperature increase changed.
4. To transfer gasoline liter to kilogram, divide its volume into density. The average values of density independent of temperature are regulated by the state and the approved Ministries of Industry and Energy.
