Study Notes
Thermodynamic Properties
- Common properties include pressure (p), temperature (T), volume (V), mass (m), specific enthalpy (h), and internal energy (U).
- Distinction between properties and quantities that depend on the process: examples include work and heat.
Property Classification
- Extensive properties: these are additive and include mass (m) and volume (V).
- Intensive properties: these are non-additive and involve specific quantities like pressure and temperature.
Thermodynamic Processes
- Steady-state systems: conditions where variables do not change over time, described by mass flow rates and continuity equations.
- Unsteady systems experience fluctuations in parameters over time.
Flow Types
- Mass flow rates: the amount of mass passing through a section per unit time, essential for steady flow calculations.
- One-dimensional flow simplifies analysis by assuming uniformity along a flow path.
Control Volume
- Control volume formulation helps in analyzing flow in and out of a system boundary.
- Characteristics of flow: steady-state conditions ensure mass flow remains constant across sections.
Continuity Equation
- Basis for analyzing fluid dynamics, ensures mass conservation in fluid systems.
Effects of Pressure and Temperature
- Pressure drops and temperature variations can affect flow velocity and thrust in engines, crucial for performance analysis.
- Ambient effects on velocity are considered when analyzing engine performance and efficiency.
Key Concepts in Fluid Dynamics
- Thermodynamic relationships: connections among various properties that dictate system behavior under different conditions.
- Relationship between flow rates and external factors, such as inlet and outlet pressures, contributes to understanding thermodynamic cycles.
