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.

why PH scale range is 14? why it is not less or not greater than 14? solution of HCl or hydrogen containing liquid has a PH. but if the solution is KMnO4 here not hydrogen power does it PH? explain plz....

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.12 : You, as an engineer, buy a piece of biochemical instrument to start a servicing business. The instrument has a useful life of 3 years, that costs $60k. The instrumental business generates $100k per year. The labor costs $50k per year. The $60k new instrument depreciates in its value evenly up to 3 years, thereafter the old instrument needs to be replaced by another piece of new instrument. (i) In the first year of this engineering business : (a) what is its starting cash? (b) calculate the depreciation value of the instrument. (c) find the operating profit generated. (d) what is the capital expense of the business? (e) calculate the cash from operation. (f) calculate the ending cash. (ii) Based on the income statement of the business in the second year : (a) find the capital expense of the business. (b) what is its starting cash? (c) calculate the depreciation value of the instrument. (d) find the operating profit generated. (e) calculate the cash from operation. (f) calculate the ending cash.

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.

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.30 : A biochemical engineering sales contract adopts Cost Recovery Method in its company accounting. Gross profit is realised only when cash collections exceed the total cost of goods sold. Let Y = Original Cost Recovered, Z = Gross Profit Realised. Its property was sold at A = $500k with cost of B = $300k. Its engineering accountant receives cash of C = $240k in first year, D = $180k in second year and E in third year. (a) Find the values of Y and Z in : (i) first year; (ii) second year; (iii) third year. (b) What is the exact value of E if all cash has been fully received from sales?
