* An explanation of the term "equivalent" angle of repose is given in the notes of DIN 22101.
The theoretical volume flow lvat a conveying speed v is calculated as follows from the values (lv)v =1 m/s according to the above table: lv =v(lv)v =1 m/s.
The conversion of the volume flow lv (quoted in m/h) to a amss flow lm (quoted in t/h) is calculated with bulk density p of the material handled (quoted in t/m) according to table 1: lm = lvp.
