surgng is revarsal of flow accompained with pr drop in
centrifugal or axial compressors

Answer / mubashar ali

Its the reversal of flow in case of centrifugal compressors.

Answer / satish yadav

low suction flow and high discharge press. then surging will occur

Anti Surge is a process witnessed only in Centrifugal
compressors as Kinetic Energy of the fluid is converted
into the Pressure energy.
Surging is not witnessed in Reciprocating Compressors, as
they are positive displacement Equipments where the
pressure increased is by volume reduction, hence providing
anti surge in reciprocating is not envisaged and not proper.
Anti Surge is witnessed when the flow to the Centrifugal
Compressor is reduced or the density of the fluid entering
the Compressor is altered to greater extent, pressure is
reduced to a lower extent. the surge valve opens and
increases the flow to the suction there by bringing back
the condition to normal operation there by saving the
equipment from damage.
Spill back on the other hand is one way of controlling the
exit flow to the downstream section from the compressor.
One should not confuse with surge control valve and spill
back controller

Answer / ramana reddy

The operation of a compressor at flows lower or output
pressure more than that at a "surge line" causes unstable
compressor operation. "Surging" occurs

MASS TRANSFER - EXAMPLE 4.3 : According to Adolf Eugen Fick (1829 - 1901) : rate of diffusion v increases with less wall thickness t, increased area A and decreased molecular weight of a fluid M. The diffusion constant D decreased with increasing M. (a) By assuming v, t, dP, A, M and D changes proportionally of each other, find the equation of v as a function of t, dP, A and D. (b) The ratio of self diffusion constant D, at T = 273 K and P = 0.1 MPa, for gases B and C are 1.604 : 0.155. If only 2 gases exist in such a system : hydrogen and nitrogen, find the type of gas for B and C with reference to their molecular weights M. (c) By using the equation of kinetic energy 0.5 MV = constant where V = square of v, find the ratio of V for B and V for C, or V(B) / V(C), as a function of M(B) and M(C), where M(B) is molecular weight of B and M(C) the molecular weight of C : Graham's Law of Diffusion.
