potential flow, ideal fluid, definition 8 Jun 2012 | 12:28 pm
Ideal fluid is incompressible and it is having zero viscosity. Flow of Ideal fluid is known as potential flow. Potential flow is highly developed. Main characteristics of potential flow are: No eddi....
What are the units of Dynamic Viscosity? 7 Jun 2012 | 12:07 am
Dynamic viscosity has the units of cP (Centi Poise), Poise(P) or in M.K.S units it has the units Kg/m.s.
what is a fluid, define fluid 7 Jun 2012 | 12:05 am
Fluid is a substance which does not resist distortion. In the sense it does not offer any resistance to the force which is going to deform the fluid. Examples: liquids and gases are fluids.
What is Elutriation ? 31 Jan 2012 | 05:02 pm
Elutriation: It is a separation method, which depends on the settling velocity of the particles in the fluid. In this process of separation, the material is placed in a rising fluid having a fixed up...
What is jigging and where it is used ? 28 Jan 2012 | 09:54 am
Jigging: Jigging is a separation method in which the particle are separated by using the density difference between them. Jigging is a method of gravitational preparation of natural resources, bas....
When reflux ratio to the column is minimum and zero, what are the requirements in column 28 Jan 2012 | 09:43 am
When reflux ratio is minimum, column requires maximum number of trays and minimum reboiler load for a required separation. To avoid this problem of infinite trays we use optimum reflux ratio. When re...
