Isentropic Power for a Double Acting Compressor:
- A double-acting compressor performs work on both sides of the piston in each cycle, effectively doubling the work done per revolution compared to a single-acting compressor.
- This results in increased efficiency and reduced power consumption for the same output.
Given:
- W = Work required by the compressor
- N = Speed of the compressor in RPM
Calculation:
- Work per revolution for a double-acting compressor is 2W (because work is done on both sides of the piston).
- Convert RPM to revolutions per second (rps):
- Speed in rps = N / 60
- Power (P) is defined as work done per unit time:
- P = Work per revolution × Speed in rps
- Substituting the values:
- P = 2W × (N / 60)
- P = 2WN / 60
