) and D is the pump/motordisplacement per radian. (In practice, the pressure in the reservoir is significantly less than thatin the accumulator, so we set Fp = paccumulator = p.) The volumetric flowrate through thepump/motor is Q = y h D.The pump/motor performance is linked to the accumulator thermodynamics through the energyequation relating the time rate of change of internal energy of the accumulator gas to the rate at dT dVwhich work is done by the gas: mcv ? /p . Here, m is the gas mass, cv is the constant- dt dtvolume specific heat for the gas, p is the gas pressure, and V is the gas volume. This equationassumes adiabatic behavior. In many

efficiency of the anaerobic digestion process is controlled by: ‚ The type of waste digested ‚ It’s concentration ‚ It’s temperature ‚ The presence of toxic materials ‚ The PH and Alkalinity ‚ The HRT (Hydraulic Retention Time) time available to convert waste to gas HRT = V/Q Q = volume of tank V = daily flow of gas ‚ The SRT (Solid Retention Time) time required to convert the solid to gas ( 10- 15 days) for low rate digestion and ( 20-30 days) for high rate digestionCosts Estimation:The $ amount of the anaerobic digestor can be estimated according to
