peclet number मीनिंग इन हिंदी

उदाहरण वाक्य

1. At high Peclet numbers, convection dominates.
2. At low Peclet numbers, diffusion dominates.
3. When the Peclet number is much greater than unity ( 1 ), advection dominates diffusion.
4. One way to tell if mixing is happening due to convection or diffusion is by finding the Peclet number.
5. The variation between \ phi \, and x is depicted in Figure for a range of values of the Peclet number.
6. Peclet number is defined to be the ratio of the rate of convection of a physical quantity by the flow to the rate of diffusion of the same quantity driven by an appropriate gradient.
7. If the flow is in positive direction then, peclet number P is positive and the term ( P-| P | ) = 0, so the function f ^-won t play any role in the assumption of �r and �l.
8. It requires that transportiveness changes according to magnitude of peclet number i . e . when pe is zero \ varphi is spread in all directions equally and as Pe increases ( convection > diffusion ) \ varphi at a point largely depends on upstream value and less on downstream value.
