Centrifugal pump belongs to the category of kinetic pumps,
Reciprocating pump is a type of positive displacement pump.

Answer / virendra

CENTRIFUGAL PUMPS WORKS BASED ON CENTRIFUGAL FORCE
ACTION,WHILE THE RECIPROCATING IS WORKS ON THE +VE DISPLACEMENT.

Answer / muhammad hassan arif

Actually, Centrifugal pumps give a continuous flow and on the other hand reciprocating pumps give fluctuating flow as to and fro motion is done inside it.

Answer / aurangzeb alam

in centrifugal pump high capacity and low head, while in Reciprocating pump low capacity and high head

Answer / nitin

Centrifugal pump's having some certain limit of HEAT & reciprocating pump's having no HEAD limit.

Answer / manjunath.nitw

centrifugal pumps increase the kinetic energy of fluid by rotational velocities and then convert to pressure enegry, but in case of +ve dispalcement pumps they appy pressure energy directly by piston r rotating member...:)

Answer / kirankumarrds

1.Centrifugal pump initially increases kinetic energy of the
fluid,later on it will be converted to pressure energy
because of the spiral design of the pump
2.Reciprocating pump directly adds KE to the fluid
3.Reciprocating pumps are used to deliver fluids at low flow
rates with high pressure energy,where as Centrifugal pump
delivers fluids in high flow rates at moderate pressure energies

Answer / sundar

centrifugal pump have impeller and large flow,
reciprocating pump is positive displacement pressure pump
,this have piston type.

BIOPROCESS ENGINEERING - EXAMPLE 14.1 : In differential centrifugation of cells with diameter D in centimeter, the square of D is given by D x D = [18n ln (RF / RI) ] / [ (RP - RFF) Wt ] where n is the fluid viscosity (poise), RF is the final radius of rotation (cm), RI is the initial radius of rotation (cm), RP is cell density (g / ml), RFF is the fluid density (g/ml), W the square for the rotational velocity in (radians / s) (radians / s), t is the time required to sediment from RI to RF (s). Derive an equation for W as a function for D, n, RF, RI, RP, RFF and t, with the stated units above, in radian & degree.

Heat transfer: In a steady state one dimensional conduction with no heat generation, the differential equation is d / dx (k dT / dx) = 0. Prove that T(x) = ax b, where k, a and b are constants. (b) At x = 0, T = c and at x = L, T = d. Prove that T(x) = (d - c) x / L c for boundary conditions.
