- Temperature around 3 deg C, - Density Conversion for Petroleum Products from observed temperature to 15 C without use of ASTM Table (1980 series)

-
One follower from Alaska, US has requested the formula for the subject conversion. The post gives a simple way to convert Density of petroleum products from ambient temperature  ( around 3 deg C  )  to density at 15 Deg C, in line with ASTM table 53B,  without using these table and in the field with simple calculation. See my earlier post dated 18 Dec 2016, for detail description of the procedure explained there. For areas in Norther Europe,  Canada,  Russia,  China and southern hemisphere New Zealand,  Southern Australia etc  where winter temperature is very low, this method is useful. A)    Simplified   Formula           D 15  = d o  - 10 +  C  x (   t o  – T)    Density at 15 deg c   = Density observed  - 10 + Constant x ( temp observed – T  )    Temperature unit is  C  ...

RVP Vs TVP of Gasoline

Is Reid Vapor pressure of gasoline (RVP) is same as true vapor pressure (TVP) ? What is difference between RVP and TVP value ? The blog article explain difference between RVP and TVP at slight higher technical level than common man perspectives. List of all blog articles on Petroleum QC  by RJ Patel. Reid vapor pressure  is a common measure of the  volatility of gasoline . It is defined as the absolute  vapor pressure  exerted by a liquid at 37.8 °C (100 °F) as determined by the test method ASTM-D-323. The test method measures the vapor pressure of gasoline, volatile crude oil, and other volatile petroleum products, except for  liquefied petroleum gases . RVP is stated in kilopascals and represents a relative pressure to the atmospheric pressure because ASTM-D-323 measures the gauge pressure of the sample in a non-evacuated chamber. All values are in SI units and are regarded as standards. Imperial units are for informat...

- Excel Formula-Density Conversion to 15 deg C,  table ASTM 53 B - 1980,    Excel sheet giving the Density 15 deg C figures from given observed Density and observed temperature for petroleum product as derived from ASTM tables 53 B. Density conversion to 15 deg C matches exactly with the ASTM conversion tables 1980. Lists of Android/iOs Apps developed on Petroleum Calculation - see here.      (These apps convert Density/API gravity exactly as per ASTM tables 5a, 5b, 6a, 6b, 23a,23b, 24a,24b, 53a,53b, 54a,54b to standard temperature 15 C,  20 C and 60 F.)   Example:  Observed density is 792 kg/Cu. M and observed temperature is 29 deg C. Corresponding 15 deg C for this set of data comes 802.2  kg/Cu. M Excel Worksheet - green color cells  observed density and observed sample temperature are variables and Red color digits are the answer - density at 15 deg C.  Apps developed on Petroleum Calculations - see here. ...

British Airways flight BA 38 accident and Aircraft Jet A-1 fuel System - part 5 This is in continuation of  " British Airways flight BA 38 accident and Jet A-1 fuel temperature - part 4"  a blog series for understanding Aviation turbine fuel’s role in modern civil flights specially  behavior of water in fuel  to mitigate it’s adverse effects during flight, including at high altitude where water will turn into ice. From fuel supplier’s perspective, it is interesting to know the aircraft fuel system which handles water (sumps in tanks, water scavenger pumps), removes external impurities from fuel (strainers-filters), fuel temperature indicators, fuel heater etc. An aircraft fuel system enables fuel to be loaded, stored, managed and delivered to the propulsion system of an aircraft. Fuel systems differ greatly from aircraft to aircraft due to the relative size and complexity of the aircraft in which they are installed.  In a modern, ...
