Thermodynamics COMPRESSION PROCESSESCOMPRESSION PROCESSESCompression and pressurization processes are very common in many types ofindustrial plants. These processes vary from being the primary function of apiece of equipment, such as an air compressor, to an incidental result of anotherprocess, such as filling a tank with water without first opening the valve.EO 1.32Apply the ideal gas laws to SOLVE for the unknownpressure, temperature, or volume.EO 1.33DESCRIBE when a fluid may be considered to beincompressible.EO 1.34CALCULATE the work done in constant pressure andconstant volume processes.EO 1.35DESCRIBE the effects of pressure changes on confinedfluids.EO 1.36DESCRIBE the effects of temperature changes onconfined fluids.Boyle'sand Charles'LawsThe results of certain experiments with gases at relatively low pressure led Robert Boyle toformulate a well-known law. It states that: the pressure of a gas expanding at constant temperature varies inversely to thevolume, or(P1)(V1) = (P2)(V2) = (P3)(V3) = constant.(1-40)Charles, also as the result of experimentation, concluded that:the pressure of a gas varies directly with temperature when the volume is heldconstant, and the volume varies directly with temperature when the pressure isheld constant, or.(1-41)V1V2T1T2orP1P2T1T2Rev. 0Page 97HT-01
