Question

A pressure gauge is calibrated form 0–50 kN/m2. It has a uniform scale with 100 scale divisions. One fifth of the scale division can be read with certainty. The gauge has a

Answer 1

Benn.. cartocated.... by 050kN/ M2. 25/

Answer 2

Given:

Pressure gauge can measure from $0-50 kN/m^2 = 0 - 50,000 N/m^2$

Number of divisions = 100

Least count = $\frac{1}{5}^{th}$ of the scale division

To Find:

Resolution of the gauge.

To Calculate:

Resolution refers to the smallest reading that can be taken.

There 100 divisions in the gauge which means that

1 division refers to  $500 N/m^2$

Of this division, $\frac{1}{5}^{th}$ division can be ready with certainty. This means the resolution of the gauge is:

$100 N/m^2 = 0.1 kN/m^2$
