Transcript Thermodynamics I

Fluid Dynamics
 Continuity equations – conservation
of mass
 Bernoulli Equation – simple
conservation of energy
 Lacks
• Accounting for devices which add or
extract energy from stream
• Fluid friction
RTT
 Generalized equation to analyze
control volume
 B: extensive property
• Mass
• Energy
• Momentum
RTT
 B – mass: continuity equations
