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.

MASS TRANSFER - EXAMPLE 4.2 : In a non-dilute absorber, graphical method is used to represent the process. In an X - Y coordinate system, X-axis represents mole of carbon dioxide / mole of water and Y axis represents mole of carbon dioxide / mole of nitrogen. The inlet gas stream consists of 8 mol % of carbon dioxide in nitrogen. (a) Find the S / G minimum as a slope that goes through the point (0, 0.0304) and (0.0000488, 0.086957). (b) Find the actual slope of operating line when it is 1.5 times the S / G minimum! (c) Find the value of x for inlet gas stream when y = 1640 x, y is mole fraction of carbon dioxide in nitrogen.

ENGINEERING PHYSICS - EXAMPLE 30.2 : The Planck-Einstein relation connects the particulate photon energy E with its associated wave frequency f to produce E = hf. Let h to be the Planck constant. The frequency f, wavelength L and speed of light c are related by E = hc / L. With p denoting the linear momentum of a particle, the de Broglie wavelength L of the particle is given by L = h / p. (a) Find the equation of E as a function of p and c. (b) If E has a unit of electron-volt and f has a unit of 1 / second, then what is the unit of h?

ENGINEERING MATERIAL - EXAMPLE 12.2 : At 150 degree Celsius, a mixture of 40 wt % Sn and 60 wt % Pb present, forming phases of alpha and beta. Chemical composition of Sn at each phase : CO (overall) : 40 %, CA (alpha) : 11 %, CB (beta) : 99 %. (a) State 2 reasons for the existences of alpha and beta phases for the mixture of Sn - Pb at 150 degree Celsius. (b) By using Lever Rule, calculate the weight fraction of each phase for alpha, WA = Q / (P + Q) and beta, WB = P / (P + Q) where Q = CB - CO and P = CO - CA.
