Determination of surface tension of given liquid by drop count and drop weight method
Answers
Answer:
'drop') is one of the most common methods for measuring surface tension. The principle is to measure the weight of drops of a fluid of interest falling from a capillary glass tube, and thereby calculate the surface tension of the fluid.
Answer:
Surface tension is the ability of a liquid's surface to resist an external force because of the cohesiveness of its molecules.
Explanation:
How will you use the drop count method to calculate the liquid's surface tension?
The idea is to calculate the fluid's surface tension by weighing drops of an interesting fluid that are falling from a capillary glass tube. By counting the drips as they fall, we may calculate their weight. We can calculate the surface tension from it.
How can surface tension be determined from drop weight?
Surface tension can be measured with accuracy and simplicity using the drop weight method. In order to measure the combined volumes of the primary and satellite drops that are generated, a liquid of density Q is dripped into the air from a capillary with a radius R at a low flow rate.
Thus, a layer of liquid will act as an elastic sheet or skin due to a force called surface tension.
