Question

Determine the method of measuring the angle of repose? ​

Answer 1

• Stop running the fabric once the pile reaches a preset height or the bottom a preset dimension.
• Rather than commit to living the angle of the ensuing cone directly, divide the peak by the dimension of the bottom of the cone.
• The inverse tangent of this magnitude relation is that the angle of repose.
• Revolving cylinder/drum technique. The revolving cylinder/drum technique is employed to see the dynamic angle of repose, which is sometimes a minimum of three to 10° but the static angle of repose and is commonly associated with the segregation phenomena of granular materials.
• Check the Attachment for the angle of repose:

Answer 2

Method of measuring the angle of repose:

• As we know that is the maximum possible angle between the surface of the pile of powder and the horizontal plane.

• For example, dry sand has an angle of the response of 35 degrees.

• Gravel has an angle of the response of 40 degrees.

• It can be determined by the following method,

                         tanθ=h/r

                         θ=tan-1(h/r)

        θ = Angle of repose.

        h = Height of pile.

        r = Radius of the base of the pile.

• The methods of measuring the angle of repose are:

        1. Fixed funnel method.

        2. Titling box method.

        3. Revolving cylinder method.
