- 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. ...

- Flash Point Prediction - Petroleum Products Blending - Calculation formula and table How to predict Flash point of resultant product after blending two stocks ?  or  how to get volume required of products to get desired  blended product Flash Point ? Many times flash point improvement is desired by blending higher flash petroleum product to lower Flash Point Product at Petroleum storage depots. List of all blog articles on Petroleum QC  by RJ Patel. Following table and formula can be used to predict the desirable variable figure of  volume of product or flash point.   In the table below against Flash Point Deg C some constant number " A " is listed in next column. Flash Point   C A Flash Point C A Flash Point  C A 20 3281 50 306 80 45 21 3004 51 285 81 43 22 2752 52 266 ...

- An App for Kin. Viscosity Calculator - blend of Petroleum Products

-
Image
This App covers the kinematic Viscosity in cSt units, blending of petroleum products. Range of viscosity here is for diesel fuels however, it can cover larger range. Readers may like to try and comment. As most of readers aware, viscosity is not additive property like say density or Sulphur content in petroleum products. The principle is based on viscosity index as explained in my article published earlier. App for blending petroleum products for  density, Sulphur Content, Benzene Content, etc (Additive properties)  may be accessed here. Similar Apps on Petroleum Calculations developed by RJ Patel- see here. Kin. Viscosity blend Calculator You can obtain this app by writing to rjpatelioc2014@gmail.com.

- Patel's Density Conversion App for Petroleum products from observed temperature to 15 C, 20 C or any desired Temperature

-
Image
A practical situation like designing of pipeline, pumps etc in oil industry require the density of petroleum products at the likely temperature  at which the products will flow. Thus the exercise is when the density is taken at observed temperature say 19 deg C and the what will be the converted density at say 27 deg C? The answer is provided in a single step, in the app developed here. Similar Apps on Petroleum Calculations developed by RJ Patel- see here.   Earlier,  various Density conversion Apps and procedures are blogged for petroleum products and crude Oil.  Here now, an app is presented for density conversion from observed temperature to any desired temperature say 15 C or 20 C or 27 C or  any temperature T. The conversion uses relationships from ASTM 53b tables for petroleum products.  You can obtain this app by writing to rjpatelioc2014@gmail.com. Author's Profile  clik here.             ...
