P i = ideal power consumption (W). AC Power Calculator. Capacitor Energy (E) And RC Time Constant Calculator. The wattage is often listed on your electrical devices. Using actual time-based billing rates will provide a more accurate power cost than the composite rate. How these metrics are tested, however, varies greatly, which impacts the results. STEP 2. Please use the calculator below to achieve an understanding of the kWh consumed (or saved) in your compressed air system. From the table above, the conversion factor for 250° and 6500 ft. altitude is 1.71. Whereas in Alternating Current, Electric charge in alternating current changes direction periodically. These equations will give the user a better understanding of how performance for a positive displacement blower is calculated. In order to evaluate blower operating costs, the load profile, or … Power consumption at different air volumes and pressure increases are indicated below: The FALCO 300 VFD blower is equivalent to 10 HP at full capacity and 2 HP at standby The FALCO 600 VFD blower is equivalent to 15 HP at full capacity and 3 HP at standby Electric Power Cost 2. The above AC power calculator is designed in a user friendly manner to perform calculations. dp = total pressure increase in the fan (Pa, N/m 2). The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt: About this page: Electricity cost calculator The calculations are based on the device wattage and electricity price per kilowatt-hour (kWh), that your local utility company charges.
