ANS:C - resolving power of telescope

Resolving power is defined as the ability of a microscope or telescope to distinguish two close together images as being separate. An example of resolving power is how well a telescope can show two stars as being separate stars.

That means C option is right.

ANS:A -

ANS:A - < 1 and ≈ 1

The Schmidt number (𝑆𝑐Sc) for pure air at atmospheric conditions is approximately greater than 1, indicating that momentum diffusivity is greater than mass diffusivity in air. This is because air is a mixture of gases, and the molecular weight of the gases present in air differs from that of individual gases. The Lewis number (𝐿𝑒Le) for pure air is approximately equal to 1. The Lewis number represents the ratio of thermal diffusivity to mass diffusivity. For most gases at moderate temperatures and pressures, the thermal diffusivity and mass diffusivity are of the same order of magnitude, resulting in a Lewis number close to 1. Therefore, the correct option is:

1 and ≈ 1

ANS:A - Fluid flow at the inlet to a nozzle

The example that exemplifies a three-dimensional fluid flow is: Viscous fluid flow between converging plates

Explanation:

1. Fluid flow at the inlet to a nozzle:
   • This typically represents a two-dimensional flow situation where the flow can be considered to occur primarily in two dimensions (axial and radial in the case of a nozzle).
2. Fluid flow between parallel plates:
   • This example usually involves a two-dimensional flow scenario where the fluid flows predominantly in the gap between the plates with uniform conditions along the direction perpendicular to the plates.
3. Viscous fluid flow between converging plates:
   • In this case, the plates are converging, which introduces a variation in the flow across the span of the plates. The flow field in this situation can vary significantly in all three dimensions (x, y, and z directions), especially if the plates are not infinitely long. Therefore, this scenario exemplifies three-dimensional fluid flow where the flow varies in all spatial directions.
4. None of these:
   • This option would be correct if none of the given examples exemplified three-dimensional fluid flow. However, viscous fluid flow between converging plates does demonstrate three-dimensional characteristics.
