time was not calculated at the right point so the poits of the graph were chaned
SO that the oil cup gets uniformly heated from all the sides
Melde’s experiment is ideal to study the behavior of standing waves. Students can even visually determine wavelength, period and amplitude of waves. A string undergoing transverse vibration illustrates many features common to all vibrating acoustic systems just like the vibrations of a violin or guitar string.
today i observed errors between puppy dial reading & height gauge dial reading. this was 10μ to 20μ when we go to .1 mm
An equipment is any laboratory experiment material which mechanically uses current like a pH meter,electric weighing machine etc while apparatus is any other laboratory experiment material which doesn't mechanically use current like thermometers ,burette ,pipette,
In a lab experiment, I found the hardness of a sample of C-1018 Annealed carbon steel to be 73.58 (averaged over 6 runs) on the HRB scale.

REDWOOD'S Viscometer is used to find out the viscosity of an standard rape oil and any of the fluids . The viscometers are classified into 4 types they are 1. Saybolt Viscometer 2. Engler Viscometr 3. Barbey Viscometer & 4. Redwoods Viscometer
In a redwood viscometer, A and B are constants used in the formula to calculate the viscosity of the fluid being tested. The formula is viscosity = A + B * time in seconds. The values of A and B are specific to the design of the redwood viscometer and are typically provided by the manufacturer.
The redwood viscometer was invented by Norman Henry Redwood, a British chemist and engineer, in the late 19th century. It was designed to measure the viscosity of liquids, particularly petroleum and related products.

Because it is the most convenient device as far as protection and accuracy is concerned.
I don't even know what it is so obviously it does not feature in my daily life.
A standard British-type viscometer in which the viscosity is determined by the time, in seconds, required for a certain quantity of liquid to pass out through the orifice under given conditions; used for determining viscosities of petroleum oils.
if we put viscometer horizontally, movement of liquid in the tube is not properly and time required by liquid which helps in calculation of viscosity of fluid
Errors in viscometer measurements can arise from several sources, including calibration inaccuracies, temperature fluctuations, and improper sample handling. Instrumental errors may occur due to wear and tear or defects in the viscometer design. Additionally, the presence of air bubbles or impurities in the fluid can lead to erroneous viscosity readings. It's also important to ensure that the sample is homogeneous and at the correct temperature to minimize variability in results.
