the difference in the volumes between beakers and measuring cylinders as per calibrations on them is due to different diameters of the beaker and measuring cylinder. Both the apparatus are cylindrical and for a cylinder the formula for volume is: volume = TTr2l, where r=radius, l=length. So, if the radii of a beaker and measuring cylinder are different then the length or height of the calibrations also need to change accordingly to contain the same volume of fluid.

Why can sulphuric acid be added with a measuring cylinder instead of a pipette?
Sulfuric acid is highly corrosive, so it can be added using a measuring cylinder because it is more resistant to the acid's corrosive properties compared to a pipette. Using a measuring cylinder allows for easier and more accurate measuring of larger volumes of sulfuric acid compared to a pipette.
What is the difference between pipette and graduated cylinder?
A pipette is a more precise measuring tool used for transferring small volumes of liquid accurately, while a graduated cylinder is used to measure larger volumes. Pipettes typically have a finer scale for precise measurements, while graduated cylinders are suitable for general volume measurements.
What is more precise a pipette or graduated cylinder?
A pipette is generally more precise than a graduated cylinder. This is because pipettes are designed to deliver specific volumes of liquid accurately, while graduated cylinders are typically used for measuring approximate volumes.
What is better to use in measuring smaller volumes of liquids the graduated cylinder or the pipette?
For measuring smaller volumes of liquids, a pipette would be better as it offers higher precision and accuracy compared to a graduated cylinder. Pipettes are designed to dispense and transfer specific volumes of liquids accurately, making them ideal for precise measurements in laboratory settings.
How do you calibrate a volumetric flask?
To calibrate a volumetric flask, you need to fill it with a known volume of liquid, usually water, at a specific temperature. Then, you measure the actual volume of liquid in the flask using a calibrated measuring device, such as a graduated cylinder or a pipette. The difference between the known volume and the measured volume is the calibration error, which can be used to adjust the accuracy of the flask.

Measuring 27 ml of liquids?
27 mL of liquid can be measured with a graduated cylinder, a burette or a pipette.
How do you calculate inaccuracy of an pipette?
To calculate the inaccuracy of a pipette, you would compare the actual volume dispensed by the pipette with the desired volume. This can be done by using a calibrated scale and measuring the difference between the intended volume and the dispensed volume. The inaccuracy can be expressed as a percentage of the intended volume.
Why measuring cylinder is more precise than pipette?
Precision describes the repeatability of results, i.e. whether you get the same answer each time you measure something. Used correctly, there is no reason why a measuring cylinder would be the more precise. The exception is if you are using an inappropriate size of pipette, as it's difficult to be precise near the bottom of its range. Too large a measuring cylinder could also be imprecise.
Is measuring pipette better than transfer pipette?
yes

What are measuring apparatus in analytical chemistry?
Examples: analytical balance, spectrophotometer, titrimeter, coulometer, emission spectrometer etc.
What tools are best when measuring liquids in a lab?
A graduated cylinder is appropriate for "normal" quantities. You may need a micro pipette for very small quantities.
What is better to use in measuring smaller volumes of liquids the graduated cylinder or the pipette?
