Most equipment may correctly operate at 0.6 0.65 Mpa, except one which needs 0.8 0.85 Mpa with a small air flow requirement (roughly 10% of the total air flow). Throttling valves are used to reduce the pressure to the end user requirements. Evaluate the energy saved if the air-compressor plant operates at a lower pressure, 0.7 Mpa, to supply the main equipment. The user at 0.8 0.85 Mpa will be supplied with a separate air compressor. answer (20%, for 5000h/yr energy saved is 95492 kWh/yr). am interested in the working and formulas
