(Redirected from EFI System partition) The EFI system partition (ESP) is a partition on a data storage device (usually a hard disk drive or solid-state drive) that is used by computers adhering to the Unified Extensible Firmware Interface (UEFI).
As much as 80 to 90% of the electrical energy used by an air compressor is converted to heat. A properly designed heat recovery unit can recover 50 to 90% of this heat for heating air or water.
Total Compressed Air Costs @ $0.06 /kWh. A 100 scfm application costs $1.22 per hour to support or $10,655 per year at 8760 hrs. Or, $0.20 per 1000 scf. 1 HP air motor costs - $3,516 per year (8760 hrs).1 HP electric motor - $426 per year. Energy savings on the demand side of the system are at a factor of.o get 1 hp work from an air motor requires approximately 30 scfm inlet air at 90 psig. which requires 6-7 hp at the compressor shaft to produce this compressed air. assuming a 90% efficient motor, this translates into 7-8 hp of electrical power to deliver 1 hp of compressed air to the plant floor.
