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.

ENGINEERING DRAWING - EXAMPLE 18.3 : Autocad computer program is used to draw a pipe that is used to transport natural gases for processing. Actual length of the pipe is 10 metres. The pipe has cross sectional area of circle in shape with measured circumference of s = 3 metres. (a) If 10 units are used to represent the actual length of the pipe in computerised engineering drawing, find the diameter of the pipe, d that will be shown in the engineering drawing. (b) If one unit in the program equals to 1 centimetre, find the scale used in the computer program.

REACTION ENGINEERING - EXAMPLE 13.2 : A batch reactor is designed for the system of the irreversible, elementary liquid-phase hydration of butylene oxide that produces butylene glycol. At the reaction temperature T = 323 K, the reaction rate constant is k = 0.00083 L / (mol - min). The initial concentration of butylene oxide is 0.25 mol / L = Ca. The reaction is conducted using water as the solvent, so that water is in large excess. (a) Let the molecular weight of water is 18 g / mol and the mass of 1 kg in 1 L of water, calculate the molar density of water, Cb in the unit of mol / L. (b) Determine the final conversion, X of butylene oxide in the batch reactor after t = 45 min of reaction time. Use the formula X = 1 - 1 / exp [ kt (Cb) ] derived from material balance. (c) Find the equation of t as a function of X.

Question 88 - In the calculation of the growth of bacteria, colony forming unit (CFU) in serial dilution is used. In a laboratory, viable count assay is used to estimate CFU. Formula applied is CFU / mL = (number of colonies x dilution) / (amount plated, in unit mL). Acceptable plate count is either between 20 and 200 or between 30 and 300 according to 2 different references. A wastewater sample of 200 ml is added to and mixed with 1.8 L of sterile water. Another 200 ml of the mixture is added to and mixed with 1.8 L of sterile water. (a) Calculate the dilution of first mixture and the dilution of the second mixture. (b) 100 microlitres of wastewater samples from the first mixture and the second mixture are placed separately on 2 different alga plates. The first plate has 250 colonies and the second plate has 23 colonies. Calculate the average CFU / mL.
