Just to let you know, the developer of this tool has a more enhanced version on their website, where you can find corrections for 15 C, API to Density conversions, volume interpolation, and more. Im an electeical engineer. endobj You measure a sounding value of 112.4 Cm with a trim of 1.7M, you will enter the following: Measured Gauge: 112.4 Trim: 1.7 Lower Volume Gauge: 112.0 You enter 112.0 because 112.0 is the lower listed boundary for your observed measurement of 112.4. Using a mean value of 0.674 or 0.67 as correction factor results in renal volumes that are 100% and 99.5%. 2 m 3 of air is heated from 22 o C to 43 o C. The volume correction factor is 1.08 and the new volume can be calculated as (2 m 3) 1.08 = 2.16 m 3 Your email address will not be published. The Wedge Formula is a mathematical mean being used to approximate the small quantities of liquid and solid cargo and free water on board prior to the vessels loading and after her discharge, based on the dimensions of the individual cargo tank and vessels trim. as per surveyors calculation. Thanks. Temp diff then will be 30 and density is 0.0204. Volume Correction Factor (VCF) The Correction for the effect of Temperature on Liquid (CTL). One very important reason we perform calibration is to determine the error and at the same time, the corrections to correct the error afterward. Before commencing of bunker operations, confirm the temperature at which the bunker is to be received and note down the standard density of the fuel oil. Some suppliers use the term weight in vacuum, as in normal condition air give bouncy according to bunker calculation programs formulated by different supplier this weight in vacuum will be .0011% more than in normal condition. The Final UUC Reading will become now your final value to be applied during your measurement process. T =temperature of oil in bunker tanks in degree Celsius, The volume correction factor of air at higher or lower temperatures than normal air: 2 m3 of air is heated from 22oC to 43oC. Volume correction factors can be used to calculate the volume of a product at base temperature (15C/59F) if you know the density and volume at another temperature. Pb = Base Pressure or Pressure Base. Webby adjusting a short-term traffic count with weekly and monthly factors. WebVolume correction factors diesel fuel . . endobj The volume of a definite quantity of bunker increases with an increase in temperature whereas its weight remains the same.

In this way ERROR is now compensated (ERROR =0), our actual value will now equal to the Standard value, therefore, accuracy was increased. 0000130861 00000 n If you like what you read, please share, subscribe and Buy Me A Coffee. The Wedge Formula is to be used only when the oil liquid does not touch all bulkheads of the vessels cargo tank, that is to say the liquid oil lying in small pools among the bottom sediment. What is a Correction Factor in Calibration? Only emails and answers are saved in our archive. And why? Actually, Im a fresh graduate frm the Petroleum Training Institute, Nigeria. In practice is the GSV the GOV multiplied by the volume correction factor (VCF) obtained from the appropriate ASTM/IP Petroleum Measurement Tables. I so much love petroleum measurements with passion. Such a method will provide a clearer indication as to the type and nature of the residues on the cargo tank floor as well as provide much clearer indications as to the profile of the residues within the cargo tanks. If rapid-acting Average Daily Traffic (ADT) - The total traffic volume during a given time period (more than a day and less Total Calculated Volume (TCV) is the gross standard volume plus the free water measured at the temperature & pressure prevailing. And Happy voyage to all. This is very important when finding out from Table 54, since the density provided there is in Air and hence same must be used. 0000002535 00000 n WebVolume Correction Factor (VCF) CTL, commonly referred to as VCF, is a standardized computed factor used to correct for the thermal expansion of liquids, primarily, Example of Fpv Effect Lets consider Natural Gas with a typical gas composition, at the 5.0 psig and 60 deg F such as in our example above. trailer Entrained material within the oil bulk, including solid particles and dispersed water, also sometimes known as base sediment and water (BS&W).
