It is named after the scientist Ralph J. Carr, Jr. The Carr index is calculated by the formula , where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder after "tapping down". It can also be expressed as .

The Compressibility .Remove any material from the sides of the cup, and determine the weight, M, of the powder to the nearest 0.1%. Calculate the bulk density, in g/mL, by the formula: (M)/(V0) in .Calculation formula of Carr Compressibility Index = 100 X [ (P tapped -P bulk) / P tapped] Calculation formula of Hausner Ratio = P tapped / P bulk. Where: P tapped - Tapped .
The popular empirical powder flowability criteria scaled with the Hausner ratio or Carr index are theoretically found only to work at special conditions and more universal criteria .carr's index formula Iba pa Carr Index (CI%, strength, stability, and compressibility) CI = ((Pb – Pt)/Pt) <0.10: Excellent flow : 0.26–0.31: Poor flow: Hausner ratio (HR, inter-particulate friction, .
. The % compressibility of a powder was a direct indicator of the possible strength and stability of a powder arch or bridge. Each formulation's Carr's index was computed .
Method III ferences are reflected in the Compressibility Index and the Hausner Ratio. Apparatus and Procedure—Proceed as directed in Compressibility Index—Calculate by the formula: Method III—Measurement in a Vessel for measuring bulk density using the measuring vessel equipped with the cap 100(V 0 − V F)/V 0 shown in Figure 2. The .The following relationships are used to calculate the two indexes. Calculation formula of Carr Compressibility Index = 100 X [ (V o -V f) / V o] Calculation formula of Hausner Ratio =V o /V f. Where: V o - Initial apparent volume. V f - Final tapped volume powder after tapping the material until no further volume changes occur.
The flowability of each sample was excellent, as Carr’s index (CI) and Hausner ratio (HR) for all samples were within 0-10% and 1.00-1.11, respectively. Although no significant differences were .Each formulation's Carr's index was computed using the equation below, and the result explanation is shown in table (10) (20). ...

Download Table | The Carr's Index and powder compressibility, correlated to the flowability. from publication: EFFECT OF PARTICLE SIZE ON TABLETY WEIGHT AND HADNESS VARIATION | In order to observe . The Carr’s compressibility index (CI, %) and Hausner ratio (HR) were also calculated based on the equations presented in Eqs. 2 and 3 and are presented in Fig. 2 for MgSt powder. The CI and HR were found to be lower for MgSt-F grade as compared to MgSt-B and MgSt-V grades. This is in accordance with density measurements.The equation for calculating the angle of repose is: tan‒1(2h/d). Using your scientific calculator, multiply height by 2 and divide this value by the distance. . Carr index greater than 25 is considered to be an indication of poor flowability, and below 15, of good flowability. Another way to measure the flow of a powder is the Hausner .
Carr Index is another measure of flowability, also calculated from the two densities of the powder. Table 2 shows the flow character based on both Hausner ratio and Carr Index (Carr, 1965). .
(1) Carr RL. Evaluating flow properties of solids. Chem Eng1965; 72:163-168. Experimental considerations for the compressibility index and Hausner ratio Compressibility index and Hausner ratio are not intrinsic properties of the powder, that is to say, they are dependent upon the methodology used. The existing literature
It is calculated by the Hausner ratio and Carr’s index (formula mentioned in Table 3) to determine the flow behaviour of powder-based drugs to calculate the density at the preformulation stages . 3.2.5 Crystallinity and polymorphism.If the values of Carr Index and angle of Repose are very far, then it can be an indication that deeper work should be done to assess the characteristics of powder B and use rigorous methods for the design. 4. Electrostatics. .
A Carr index greater than 25 is considered to indicate poor flowability, and a value less than 15 indicates good flowability. Another way to measure powder flowability is the Hausner ratio, which can be expressed as: H. = ρ T. / ρ B. {\displaystyle H=\rho _{T}/\rho _{B}} . Both the Hausner ratio and the Kerr index are sometimes criticized for .
A higher Carr's Index or Hausner's ratio indicates that the powder is more cohesive and less free-flowing. Carr's index or a Hausner's ratio more than 25 or 1.34, respectively, generally indicates poor flow characteristics (Carr, 1965; Hausner, 1967; Kaleem et al., 2020).

Table 1 illustrates the specifications about the Carr's index and the Hausner ratio. Both CI and HR were calculated from the loose and tapped bulk densities of the spray dried goat milk powder .
It can be calculated from the following equation and category of carr's index given in Table 2. ©Pharmaceutical . bulk density, tapped density, index and Hausner's ratio. Developed tablets were .
11.2.2 Hausner ratio. A similar index was defined by Hausner (1967). The Hausner ratio is defined as (11.3) The relationship between the Hausner ratio and powder flow is given in Table 11.1.Because both Carr’s and Hausner’s ratios are one-point determinations, calculated from the initial and final volumes of the powder, they do not . Compressibility Index = 100 × [ (Vo − Vf)/Vo] Hausner Ratio = (Vo/Vf) Where, the unsettled apparent volume, Vo, and. the final tapped volume, Vf, of the powder after tapping the material until no further volume changes occur. The compressibility index and Hausner ratio may also be calculated using measured values for bulk density (ρbulk .
