Average particle size determination d50 from gravimetric analysis. Mesh-opening.xls

(For a given granulometric analysis (mesh size vs. Retained percentage) a table of “Mesh vs. Particle size (mesh opening)” is made. The plotted curve allows to find the particle size orresponding to a 50% retained percentage: This is the average particle size or d50 value. Evaluation of a filtrated sample properties. Gravimetric composition of a flow resulting from the joint of two flows. Rev. 09.08.2016)

Atmospheric temperature, pressure and density as function of the height above sea level.xls

(This file presents the calculation of atmospheric temperature, pressure and density as a function of the heigth above sea level, according 1976 U.S. Standard Atmosphere. It includes also an approximate method that can be applied for a range of heights 0 km.a.s.l. < H < 6 km.a.s.l. with an error less than 0.1% . Also, it is presented an equation to calculate the water vapor. pressure as a function of temperature. References included. Rev. 09.08.2018)
