Calipers are used to measure the dimension of anarticle. In measuring a section of pipe you would use an inside caliper to give the internal diameter, and an outside caliper to give the external diameter. The difference being the thickness of the pipe wall.
A protractor can be used to measure an angle.
Varier calliper
The instrument you are looking for is a compass
The instrument used to measure a angle is called a protractor!
A set of calipers.
Vernier caliper
Inside and outside calipers are used for this.
A vernier caliper
A manometer instrument is used to check the alignment of two shafts.
The instrument used to measure the diameter of spherical objects is called calipers.
A Vernier caliper, or a micrometer can measure diameter real well, and from that it's easy to calculate area.
Calipers measure the internal or external dimensions of something.

Relative roughness is a measure of the surface roughness of pipe surfaces. It is the size of the roughness scaled by the diameter of the pipe or duct. Rel Roughness=e/D; where e is the measurement of the surface roughness and D is the diameter of the pipe. It is mainly used for calculating head losses in piping systems.
The instrument which is used to measure snowfall is called a snow gauge.
No. The instrument used to measure wind speed is an anemometer.
