Air Compressors - Yearly Power Costs
Yearly power costs operating an air compressor
Sponsored Links
Yearly power costs operating an air compressor can be calculated as
C = Pbhp 0.746 ckWh hyear / μ (1)
where
C = total power costs per year (USD, - or actual currency)
Pbhp = compressor power (bhp)
ckWh = cost per kWh (USD, - or actual currencey)
hyear = Operating hours per year (h)
μ = motor efficiency
Power costs count for typical 60-70% of the total operating costs. Fixed costs counts typical 10-20 % and other operating costs counts typical 15-25% of the total operating costs.
