The desired sensitivity of a bubble tube with 2mm. divisions is 30″. What should be the radius of the level tube?
- 13.75m.
- 14.75m.
- 15.75m.
- 16.75m.
\[
R = \rho \frac{n}{\alpha_s}
\]
\[
R = \frac{206264.80″}{rad.} \times \frac{2mm.(\frac{1m.}{1000mm.})}{30″}
\]
\[
R = 13.75m. \leftarrow \text{answer}
\]
