Questions and Answers
What is the primary factor that influences the flow of fluid?
The primary factor is the pressure gradient within the fluid.
How does temperature affect the viscosity of a fluid?
Generally, as temperature increases, the viscosity of a fluid decreases.

Study Notes
Fluid Dynamics Fundamentals
-
Primary Factor Influencing Fluid Flow:
- Pressure gradient is the main driver of fluid flow, dictating the movement from high to low pressure areas.
Temperature and Viscosity
-
Impact of Temperature on Viscosity:
- Viscosity generally decreases with an increase in temperature, causing fluids to flow more easily as thermal energy breaks intermolecular bonds.
Bernoulli's Equation
-
Main Principle of Bernoulli's Equation:
- This principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy, describing the conservation of energy in fluid motion.
Role of Turbulence
-
Effects of Turbulence in Fluid Flow:
- Turbulence enhances mixing and energy dissipation but complicates the prediction of flow patterns, leading to increased drag and altered pressure profiles.
Importance of Laminar Flow
-
Significance of Laminar Flow in Fluid Dynamics:
- Understanding laminar flow is critical for applications involving streamlined flow, where layers of fluid move in parallel, reducing resistance, and improving efficiency.
