Answer:
A ratio of equivalent units
Explanation:
A conversion factor is a ratio of equivalent units and depends on which units are to be converted.
For example we want to convert 275 [mm] to inches, so we have to find the right conversion factor to allow us to work that conversion.
275 [mm] = inches = ?
![275 [mm] * \frac{1in}{25.4mm} = 10.82 [in]](https://tex.z-dn.net/?f=275%20%5Bmm%5D%20%2A%20%5Cfrac%7B1in%7D%7B25.4mm%7D%20%3D%2010.82%20%5Bin%5D)
In this case the ratio is 1/25.4 = 0.039 [in/mm]

<h2>
Option A is the correct answer.</h2>
Explanation:
For steady state we have discharge(Q) at all points are same.
Q₁ = Q₂
We know
Discharge = Area x Velocity
Q =A v
So we have
A₁ v₁ = A₂v₂
Given that
A₁ = 16 cm²
v₁ = 1 m/s
A₂ = 4 cm²
v₂ = ?
Substituting
16 x 1 = 4 x v₂
v₂ = 4 m/s
Option A is the correct answer.
