Question

Match the following.

$$\begin{array}{cccc}& \text{Column 1}& & \text{Column 2}\\ A& \text{Ideal fluid}& i& \text{Compressible and viscous}\\ B& \text{Non-uniform flow}& ii& \text{Incompressible and non-viscous}\\ C& \text{Uniform flow}& iii& \text{At any instant velocity is constant for all points}\\ D& \text{Real fluid}& iv& \text{Velocity changes from point to point at any given instant of time}\end{array}$$

• A. $A\to \left(i\right);B\to \left(ii\right);C\to \left(iii\right);D\to \left(iv\right)$
• B. $A\to \left(iv\right);B\to \left(iii\right);C\to \left(ii\right);D\to \left(i\right)$
• C. $A\to \left(ii\right);B\to \left(iv\right);C\to \left(iii\right);D\to \left(i\right)$
• D. $A\to \left(iii\right);B\to \left(i\right);C\to \left(iv\right);D\to \left(ii\right)$

Answer 1

The correct option is C $A\to \left(ii\right);B\to \left(iv\right);C\to \left(iii\right);D\to \left(i\right)$

Incompressible and non-viscous fluids are ideal fluids.
Compressible and viscous fluids are real fluids.
In uniform flow, velocity at a given instant of time is same at all points.
In non uniform flow, velocity changes from point to point at any given instant of time.
