Probably bcoz centrifugal pumps are continuous while reciprtocating pumps are discontinuous process. I think centrifugal pumps are used for viscous fluid such as oil,chemicals. Reciprocating can handle only pure water as it's valves cause frequent trouble.
Probably bcoz centrifugal pumps are continuous while reciprtocating pumps are discontinuous process. I think centrifugal pumps are used for viscous fluid such as oil,chemicals.
Reciprocating can handle only pure water as it's valves cause frequent trouble. Only receprocative pumps will be used to pump high viscous fluids like chemical and oils.
Because reciprocating pumps will give low discharge at higher ends usually in industries and oil and gas plants these are used frequently to pump the chemicals and oils. Bug pressure is inversely proportional to the area hence.. As you can see the area inside casing keeps on increasing towards outlet so according to continuity equation, velocity gets decreased. Now as per Bernoulli Principal, as velocity decreases, pressure increases.

Both centrifugal and reciprocating pumps are most common type of pumps used to move fluid and increase its pressure. Centrifugal pump which is also known as rotary pump used kinetic energy of impeller to force the fluid and increase its kinetic energy.
This kinetic energy suddenly converts into pressure energy which move fluid upward. These are used in household pumps for domestic water supply. Reciprocating pumps are one of the positive displacement pumps which contain a piston cylinder device. Water is trapped into the cylinder during suction stroke and force out during exhaust stroke.
It is mostly used to pump high viscous fluids. The basic and main difference between centrifugal pump and reciprocating pump is that centrifugal pump use kinetic energy of impeller so it continuously supply fluid but in reciprocating pump piston sucks the fluid and then pushes it out which does not gives continuous supply. There are some modified reciprocating pumps are available which gives continuous discharge. There are many other differences which are described as follow. It is mostly used for domestic purpose and where higher discharge at low head required.
These are mostly used in industries and high viscous fluid pumped at a high head. Today we have learnt about difference between centrifugal pump and reciprocating pump.

Reciprocating can handle only pure water as it's valves cause frequent trouble Reply No…can be used also for water In submersible pump That is multistage centrifugal pump.
As per ur requirement in highly viscous fluid for reciprocating pump. Reply Plz suggest me for a fluid mechanics book. Because reciprocating pumps will give low discharge at higher ends usually in industries and oil and gas plants these are used frequently to pump the chemicals and oils Reply why flow rate decrease with increase in pressure in centrifugal pumps Reply Bcz discharge rate Q is directly proportional to The AREA A.
Centrifugal pump. Reciprocating pump. It is one of the rotary pumps which used kinetic energy of impeller. It is a positive displacement type pump which is forced by piston. It continuously discharges the fluid.
It does not discharge the fluid continuously. In centrifugal pump the flow rate decreases which increasing the pressure. The pressure does not affect flow rate in reciprocating pumps. It is used for pumping high viscous fluid. It is used for pump low viscous fluid. In this pumps discharge is inversely promotional to the viscosity of fluid. In reciprocating pump viscosity of fluid does not affect the discharge rate. Efficiency of these pumps are low compare to reciprocating pump.
Efficiency is high. Centrifugal pump have problem of priming. It does not have any problem of priming. It uses impellers to transfer energy to fluid. It uses piston cylinder device to transfer energy to fluid.
They are lighter than reciprocating pumps. These are heavier compare to centrifugal pump. It gives higher discharge at low heads. These gives higher heads at low discharge. It is less costly. These are costly. These pumps required less maintenance.
These required higher maintenance. Centrifugal pumps are easy to install. These required less floor space. These pumps are difficult to install. These required more floor area.
The main difference between reciprocating and centrifugal pump is, In a reciprocating pump, the discharge is fluctuating and pulsating whereas the discharge is smooth and continuous in the centrifugal pump. Here I have listed more than 20 points to understand you in every detail manner. When we talk about pump first definition comes in mind that it delivers water or other liquid from one place to another place. A pump is a device that is used for lifting the liquid from the ground surface and delivers to the topmost upper surface. The pump converts mechanical energy into hydraulic energy. It is a positive displacement type pump where a certain volume of liquid is entered in closed volume and it discharged using pressure to the required application.

Approved Reciprocating Pump Manufacturers. Reciprocating pumps are subject to packing leaks and in such services must be fitted with a double stuffing box to provide an enclosed leakage disposal system. In the traditional piston pump the upper valve is usually situated in the piston and known as the piston valve; the lower valve is called the foot valve.
Reciprocating pumps are used where the delivery pressure of the fluid is quite large. In this article, we will discuss on Single-acting Reciprocating Pump. As the name itself indicates that it has a single component of the suction valve, delivery valve, suction pipe, and delivery pipe along with a single-piston.
Изначальный план состоял в том, чтобы сделать это незаметно и позволить Танкадо продать пароль. Сьюзан должна была признать, что прозвучало это довольно убедительно. У Танкадо не было причин подозревать, что код в Интернете не является оригиналом. Никто не имел к нему доступа, кроме него самого и Северной Дакоты. Если бы Танкадо не вернулся к анализу программы после ее выпуска свет, он ничего бы не узнал про этот черный ход. Но он так долго трудился над Цифровой крепостью, что вряд ли ему захотелось бы к ней возвращаться.
Ты видел кольцо. Двухцветный замер. Как правильно ответить. - Viste el anillo? - настаивал обладатель жуткого голоса. Двухцветный утвердительно кивнул, убежденный, что честность - лучшая политика. Разумеется, это оказалось ошибкой. В следующую секунду, со сломанными шейными позвонками, он сполз на пол.
От неожиданности Сьюзан застыла на месте. Она была уверена, что никогда не говорила с шефом о поездке.
