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.

FOOD ENGINEERING - QUESTION 23.2 : (a) A dryer reduces the moisture content of 100 kg of a potato product from 80 % to 10 % moisture. Find the mass of the water removed in such drying process. (b) During the drying process, the air is cooled from 80 °C to 71 °C in passing through the dryer. If the latent heat of vaporization corresponding to a saturation temperature of 71 °C is 2331 kJ / kg for water, find the heat energy required to evaporate the water only. (c) Assume potato enters at 24 °C, which is also the ambient air temperature, and leaves at the same temperature as the exit air. The specific heat of potato is 3.43 kJ / (kg °C). Find the minimum heat energy required to raise the temperature of the potatoes. (d) 250 kg of steam at 70 kPa gauge is used to heat 49,800 cubic metre of air to 80 °C, and the air is cooled to 71 °C in passing through the dryer. If the latent heat of steam at 70 kPa gauge is 2283 kJ / kg, find the heat energy in steam. (e) Calculate the efficiency of the dryer based heat input and output, in drying air. Use the formula (Ti - To) / (Ti - Ta) where Ti is the inlet (high) air temperature into the dryer, To is the outlet air temperature from the dryer, and Ta is the ambient air temperature.

CHEMICAL FLUID MECHANIC - EXAMPLE 3.2 : The terminal velocity of a falling object, v is given by v = sqrt [ 4g (R - r) D / (3Cr) ] where sqrt is the square root of, g = 9.81, D = 0.000208, R = 1800, r = 994.6, m = 0.000893. The Reynold number, L is given by L = rD (v) / m. The C for various conditions are : C = 24 / L for L < 0.1; C = 24 (1 + 0.14 L^0.7) / L for 0.1 <= L <= 1000; C = 0.44 for 1000 < L <= 350000; C = 0.19 - 80000 / L for 350000 < L. Find the value of v for the situation above by trial and error, ^ is power, <= is less than or equal to.
