Suspension Definition and Properties

Suspension Definition and Properties

The substance of little size particles that are insoluble in the solvent, but which are visible distinctly through the naked eye is called a suspension. Thus it is a heterogeneous mixture of two or more substances and in it, the sizes of the dispersed particles are of the order of 10-5 cm or more. The little particles can be filtered and these are temporary which have a common tendency to scatter from the medium of dispersion. There are so many examples of suspension in our common walk of life like the water of the river, smoke in atmospheric air, etc.

Properties of Suspension

  1. The suspension is a heterogeneous mixture.

  2. The particles of suspension can be seen by the naked eye and its size is of the order of 10-5 cm or more.

  3. The particles of suspension scatter a beam of light passing through it and make its path transparent (visible).

  4. The suspension is unstable because the solute particles settle down when it is left undistributed. That's why the solute can be separated from the mixture by the process of filtration. Thus when the solute (particles) is settled down then the suspension breaks and it doesn't scatter light anymore in any direction.

Limitations of Terzaghi Theory

Limitations of Terzaghi Theory The value of the coefficient of consolidation has been assumed to be constant.  The distance d of the drainage path cannot be measured accurately in the field. The thickness of the deposit is generally variable, and an average value has to be estimated.  There is sometimes difficulty 1n locating the drainage face, and sometimes thin previous seams that can act as good drainage faces are missed in the boring operations. The equation is based on the assumption that the consolidation is one-dimensional. In the field, the consolidation is generally 3-dimensional. The lateral drainage may have a significant effect on the time rate of consolidation. The initial consolidation and secondary consolidation have been neglected. Sometimes these form an important part of the total consolidation. In actual practice, the pressure distribution may be far from linear or uniform.

Comparison between VSI and CSI

Comparison between VSI and CSI In power electronic systems, inverters are an essential component that converts direct current (DC) into alternating current (AC). There are two main types of inverters used in power electronic systems: Voltage Source Inverters (VSI) and Current Source Inverters (CSI). Both have their own unique advantages and disadvantages, and the choice of which to use depends on the specific application and the desired outcome. Comparisons between voltage source inverters and current source inverters are as follows. In voltage source inverters, the input voltage is maintained constant and the amplitude of the output voltage does not depend on the load. However, the waveform of load current, as well as its magnitude, depends upon the nature of load impedance.  In current source inverters (CSI), the input current is constant but adjustable. The amplitude of output current from CSI is freelance of the load. However, the magnitude of output voltage and its undulation outp
