A variable-load piston-cylinder device contains air (cp = 1.005 kJ/kgK; cv = 0.718 kJ/kgK) at 500 kPa and T=18 oC. A paddle wheel equipped within the system and turned by an external electric motor until 65 kJ/kg of work has been transferred to the air. During this process the gas volume is quadrupled while maintaining the temperature constant by transferring heat to the gas. Determine (a) the final pressure, (b) the amount of required heat transfer (c) Show this process on a P-v diagram. Do not use Table A-17 while solving this problem

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
