Module 7: Flow through orifices, mouthpieces, notches and weirs Lesson Orifices, vena contracta, Hydraulic coefficients Lesson Discharge losses, Time for emptying a tank Lesson External and internal Mouthpiece Lesson Types of notches, rectangular and triangular notches, rectangular weirs Lesson Numericals on orifice, mouthpiece, notch and weir Module 8: Measuring Instruments Lesson Venturimeter and pitot tube Lesson The surface tension of this liquid can be strengthened by adding a little glycerine to the solution.
An approximately rectangular soap film is thus formed.
You will have to exert a force to hold the straight wire in place. How is this force related to the surface tension? In this example, since the liquid film has two surfaces exposed to air, it is helpful to think of the problem as consisting of two separate liquid-gas films that lie next to one another.
Generally, this 2 multiplier will occur in a liquid film separating a gas from a gas e. A film separating a gas from a liquid e. The surface tension of a liquid is always a function of the solid or fluid with which the liquid is in contact.
If a value for surface tension is given in a table for oil, water, mercury, or whatever, and the contacting fluid is not specified, it is safe to assume that the contacting fluid is air. The value of 3 can be determined experimentally by stretching a film of fluid and measuring the required force as in Example 1.
Surfactunts are chemicals developed to change the surface tension of a liquid for a desired purpose. Detergents and wetting agents are familiar examples of liquids with surfactant properties.
When bubbles or films are made for experimental purposes, those made from pure water are very fragile and burst easily.
