Pumps Operating in Series and Parallel:

Centrifugal pumps are joined in series or in parallel to meet certain operational requirements. They are joined in series (Fig. 10.18a) when the delivery head requirements are high as in case of pumping in high rise buildings or operating sprinkler systems etc. Two or more pumps may be joined in such a way that the delivery of one becomes the inflow into the other.




Pumps are joined in parallel (Fig. 10.18b) when they have a common source and pumping head is the same. In situations like pumping from rivers or a pond or dewatering of foundations, pumps could be joined in parallel.
The pumps will now operate against the same head H = H1 = H2 =…. If the characteristics of the pumps differ too much, this relationship may not be applicable.

General Checklist List for Pre-start and Starting up the Centrifugal Pumps.

General Checklist the Essential Steps and precautions for Pre-start and Starting up the Centrifugal Pumps . # What’s the things you Should be attention physically? # General centrifugal pump start up procedure:- Before pump start-up you must perform these tasks:- *01.  Open the suction valve , do priming by venting all the air inside the suction line by opening any vent or even the PG vent till liquid coming out then close , now you confirm no air inside the system to reduce the chances of pump getting cavitation *02.   Open any re-circulation  or cooling lines. *03.   Fully close or partially open the discharge valve, depending on system conditions. *04.   Start the driver. *05.   Slowly open the discharge valve until the pump reaches the desired flow. *06.   Check the pressure gauge to ensure that the pump quickly reaches the correct discharge pressure. *07.   If the pump fail to reach the correct pre...

What is Fire Point, Smoke Point, Freezing Point, Dew Point, Flash Point, Pour Point, Boiling Point, Bubble Point?

# Fire Point :-  The lowest temperature at which the vapor of that fuel will continue to burn for at least 5 seconds after ignition by an open flame. #Smoke Point:-   The temperature at which, under specific and defined conditions, an oil begins to produce a continuous bluish smoke that becomes clearly visible. #Freezing Point:-  The temperature at which water changes phase from a liquid to a solid. # Dew Point:-   T he temperature at which air is saturated with water vapor. # Flash Point:-  T he lowest temperature at which enough fluid can  evaporate to form a combustible concentration of gas. #Pour Point:- The lowest temperature at which the oil will pour or flow when it is cooled without stirring. #Boiling Point:-   The temperature at which the vapor pressure of a liquid is equal to the pressure of the atmosphere on the liquid. #Bubble Point:-   The temperature wh...

Industrial Catalyst And Classification.

Principle Of Industrial Catalyst And Classification Of Catalyst.   Principle Of Industrial Catalyst : An industrial catalyst is a substance that accelerates a chemical reaction without undergoing any significant change in its own chemical composition. Catalysts work by lowering the activation energy required for the reaction to occur, thereby increasing the reaction rate. They provide an alternative pathway for the reaction to take place, which requires less energy and allows the reaction to proceed at milder conditions such as lower temperatures and pressures. Industrial catalysts are used in a wide range of chemical processes, including petrochemicals, refining, polymerization, and environmental applications. Classification Of Industrial Catalyst : Industrial catalysts can be classified into four main groups: 01. Homogeneous catalysts. Homogeneous catalysts are soluble in the reaction medium and are used mainly in the production of fine chemicals and pharmaceuticals. 02. Heteroge...

Difference between LNG, LPG and NGL

✅ LNG — Liquefied Natural Gas, is gas that has been Liquified at very low temp. and is transported as a liquid. It’s Primarily methane ,NG is a mixture of HC which, when liquefied, form a clear colorless,odorless liquid; it’s usually transported and stored at a temp. very close to its boiling point at atmospheric pressure (~ -160), The actual composition of LNG will vary depending on its source and on the liquefaction process, but in all cases the major is methane with small percentages of the heavier HC such as ethane, propane, butane and pentane ,N2 may be present.  ✅ LPG — Liquefied Petroleum Gas gas that is liquid near room temperature and at some extent of pressure. This product has very little methane and butane and is primarily propane (C3),LPG is more dense (has a higher specific gravity) than natural gas ,Their common characteristic is that they can be compressed into liquid at relatively low pressures ,The two most common LPG constitutes are Propane and Butan...
