Problem 720

Air is compressed by a 15-kW compressor from P1 to P2. The air temperature is maintained constant at 258C during this process as a result of heat transfer to the surrounding medium at 208C. Determine the rate of entropy change of the air. State the assumptions made in solving this problem.

Step-by-Step Solution:
Step 1 of 3

 Anelastic (viscoelastic) material- a material in which the total strain developed has elastic and viscous components; Part of the total strain recovers similar to elastic strain. Some part, though, recovers over a period of time. Examples of viscoelastic materials include polymer melts and many polymers including silly putty. Typically, the term anelastic is used for metallic materials  Apparent viscosity- viscosity obtained by dividing shear stress by the corresponding value of the shear-strain rate for that stress  Bend test- application of a force to a bar that is supported on each end to determine the resistance of the material to a static or slowly applied load; typically used for brittle materials  Bingham plastic- a material with a mechanical
