Theoretical maximum density formula
Did you know?
WebbDensity is the unit weight of a mixture. Density is usually shown as a percent of maximum theoretical (Gmm) or the specific gravity of the in-place compacted density divided by the Gmm. Air voids is used interchangeably with density and is calculated: percent air voids = 100 – percent density. WebbFör 1 dag sedan · Bernoulli's equation along the streamline that begins far upstream of the tube and comes to rest in the mouth of the Pitot tube shows the Pitot tube measures the stagnation pressure in the flow. Therefore, to find the velocity V_e, we need to know the density of air, and the pressure difference (p_0 - p_e).
