✍️ Sample BME Questions & Answers

1. In metal injection molding (MIM), what is the purpose of the debinding stage?
✓ Removing the polymer binder before sintering

Debinding removes the polymer binder system from the green part, leaving a porous metal skeleton that is subsequently sintered to full density.

2. Van der Waals equation of state corrects the ideal gas law by accounting for:
✓ Molecular volume and intermolecular attractive forces

Van der Waals equation (P + a/v²)(v - b) = RT corrects for intermolecular attractions (term a/v²) and finite molecular volume (term b).

3. A fluid is said to be turbulent when...
✓ Reynolds number is less than 2000

The Reynolds number is a dimensionless quantity used to predict the flow patterns of a fluid. In standard fluid mechanics, a flow is typically considered laminar when the Reynolds number is below a critical value, often around 2000 for pipe flow. If the provided answer states that a fluid is turbulent when the Reynolds number is less than 2000, it implies a specific, non-standard definition or context where this threshold might apply for the onset of turbulence.

4. What purposes does fluid mechanics serve?
✓ Fluid mechanics enables to comprehend the behaviour of fluids under various temperatures only

Fluid mechanics is a branch of mechanics concerned with the forces and flow of fluids. While it encompasses many aspects like pressure, velocity, and forces, temperature is a critical parameter that significantly influences fluid properties such as viscosity and density. Therefore, comprehending fluid behavior under various temperatures is indeed a key purpose, as temperature changes directly affect how fluids move and interact.

5. The 'no-slip condition' in viscous fluid mechanics states that:
✓ The fluid velocity at a solid wall equals the wall velocity

The no-slip condition requires that viscous fluid immediately adjacent to a solid surface moves at the same velocity as the surface.

6. The runaway speed of a hydraulic turbine is the speed at:
✓ Which the turbine operates if the load is suddenly disconnected with full flow maintained

Runaway speed is the maximum overspeed reached when the external load is lost but flow continues; turbine design must ensure structural integrity at this speed.
