Vd

The index is calculated by dividing the value of what was damaged (Vd) by the total value of the properties within the landfall footprint (Vt) to get the damage ratio (D).

The term specific gas production (Gp, measured in m³ gas/m³ Vd x day) supplements the above expression by defining the digester's biogas output. pH/volatile acids

5. Biogas technique 1989

The size of the digester, i.e. the digester volume (Vd), is determined on the basis of the chosen retention time (RT) and the daily substrate input quantity (Sd).

4. Balancing the energy demand with the biogas production 1989

For a typical agricultural biogas plant, the Vd/Vg-ratio amounts to somewhere between 3: 1 and 10: 1, with 5: 1 - 6: 1 occurring most frequently.

4. Balancing the energy demand with the biogas production 1989

Specific gas production (Gp) i.e. the daily gas-generation rate per m³ digester volume (Vd), is calculated according to the following equation:

4. Balancing the energy demand with the biogas production 1989

The volumetric charge, i.e. how much substrate is added per unit of digester volume each day (Vc, measured in m³/m³ Vd x d), is given by the chosen (technical) retention time (RT).

5. Biogas technique 1989

Vd: Vg is a major factor with regard to the basic design of the biogas plant.

4. Balancing the energy demand with the biogas production 1989

Its size, i.e. digester volume Vd, can be established by

7. Planning a biogas engine system 1988

The "displaced volume" of one cylinder Vd, c (1, cm³) is the volume displaced by the piston between its lowest position, the "bottom dead center", BDC, and its highest position, the "top dead center", TDC.
