Fluids
In an adiabatic process where no heat exchange occurs between an enclosed gas and its surroundings resulting from rapid compression or expansion, which best describes how applying Bernoulli’s Principle can lead to incorrect predictions about system behavior?
Bernoulli's principle assumes steady non-viscous flow without frictional losses making perfect matches impossible in dynamic real-world scenarios like those involving rapidly-changing gas volumes temperatures.
Since Bernoulli's Principle applies only to liquids and not gases, any attempt to apply it within gaseous adiabatic processes would naturally yield erroneous results due lack applicability scope overlap.
Adiabatic processes have no impact on application viability since Bernoulli’s equation inherently accounts for all forms of internal gas work done against compressive forces.
Temperature changes caused by adiabatic processes violate Bernoulli’s assumption of constant temperature flows leading to miscalculations using standard equations.
How does increasing fluid flow speed affect static pressure in a horizontal pipe according to Bernoulli's principle?
The static pressure remains constant when fluid flow speed increases according to Bernoulli's principle because total energy stays consistent along a streamline, regardless of the change in kinetic and potential energies.
Not enough information provided to determine the change in static pressure.
The static pressure decreases as fluid flow speed increases according to Bernoulli's principle because total energy must be conserved along a streamline; increased kinetic energy implies decreased potential energy (static pressure).

What happens to the total mechanical energy when non-viscous fluids move through a pipe at steady flow?
It decreases over time.
It remains constant.
It varies depending on pipe diameter.
It increases over time.
In a closed system where no energy is lost to friction, what does the conservation of mechanical energy imply about the initial and final total energy levels?
Initial energy is higher than final energy.
Final energy is higher than initial energy.
They are equal.
Only kinetic energy is conserved, not potential.
A closed pipe filled with a uniform velocity suddenly opens into a large container. How does the changes in inside pressure correspond to the change in cross-sectional area at the opening?
Incorrect. The inside pressure remains constant.
Incorrect. The inside pressure fluctuates while moving through sections.
Incorrect. The inside pressure increases.
Correct. The inside pressure decreases due to expansion.
When calculating fluid flow, what is the basic SI unit for mass?
Mole (mol)
Ampere (A)
Liter (L)
Kilogram (kg)
What happens when internal viscous forces become significant inside a tube as an idealized incompressible liquid flows through it according to conservation principles?
The liquid slows down.
The liquid stops flowing.
The liquid speeds up.
The liquid changes color.

A properly insulated venturi meter facilitates analysis on what key factor affecting dynamic pressure readings while applying continuity and Bernoulli’s equations under real-world non-ideal flow conditions?
Water hardness levels primarily if mineral buildup potentially disrupts smooth flow dynamics affecting precise instrumentation output quality standards
The Reynolds number considering its role influencing laminar versus turbulent flow regimes which alters coefficient calculations within venturi meters
Ambient light intensity surrounding apparatus given photovoltaic sensor fluctuations may affect electronic signal transmission integrity thus modifying readouts indirectly
Pipe angle orientation since gravity-induced potential difference impacts measurement reliability if not accounted correctly during calibration stages
What effect did introducing computational fluid dynamics (CFD) software have on engineers' ability to predict fluid behavior in complex systems?
CFD allows accurate simulations that predict how fluids will behave under various conditions without physical experimentation.
It provided better visualization but did not significantly improve the precision of predictions.
The introduction made physical experiments more prevalent as CFD results often required verification.
Computational software was found too complex, leading to a preference for simplified mathematical models instead.
In a hydraulic system, how does changing the diameter of one piston affect the force exerted by another piston if all other conditions remain unchanged?
It doesn't affect the force exerted by another piston but changes its distance moved proportionally.
Changing one piston’s diameter alters only the speed at which another piston will move, keeping force constant.
Increasing the diameter increases the force exerted by another piston linearly with increased area.
Decreasing one piston's diameter decreases the work done by another piston but not its force directly.
