Experiment # 01

 Object:

Determine the capacity and thickness of a test tube by using Vernier Calliper.

Apparatus:

Vernier Calliper, Test tube.

Working Formula:

Capacity:

Thickness:

Least Count:

        Smallest Division value on Main Scale = 0.1 cm Or 1 mm

        No. of divisions on Vernier Scale = 10 div

Zero Error:

Main Scale Reading cm	Vernier Scale Reading div	Fractional Part cm	Zero Error cm

Observations:

Quantity		Main Scale Reading (MSR) cm	Vernier Scale Reading (CSR) div	Fractional Part FP = CSR x L.C cm	Total Reading TR = MSR + FP cm	Mean cm
External Diameter of Test tube	1 2 3
Internal Diameter of Test tube	1 2 3
Depth of Test tube	1 2 3

Calculation:

Thickness:

As per Requirement Space (Max: 6 lines)

Capacity of Test tube: 

As per Requirement (Max: 6 lines)

Result:

        The thickness of test tube = .............. cm

Precautions:

1. Take the readings very carefully.
2. Handle the apparatus with great care.
