    in the direct method. In the coal mass flow a reasonably high degree of accuracy can be obtained with the volumetric feeder calibration (Appendix A Sample calculation A.S) but the density and representivety of the sampled coal renders the mass flow and CV determination too inaccurate for efficiency calculations.
