Chirality – Isolation of Limonene from Citrus Fruits Introduction: Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons‚ grapefruits‚ limes‚ and tangerines contain the compound as well. The

jacks are often used to liftelevators in low and medium rise buildings. A hydraulic jack uses a fluid‚ which is incompressible‚ that is forced into a cylinder by a pump plunger. Oil is used since it is self lubricating and stable. When the plunger pulls back‚ it draws oil out of the reservoir through a suction check valve into the pump chamber. When the plunger moves forward‚ it pushes the oil through a discharge check valve into the cylinder. The suction valve ball is within the chamber and opens

The Greeks created some of the most influential pieces of literature in history. Their stories and heroes appear many times in popular culture‚ like Hercules with his amazing strength and ability to take down the most formidable beasts. However‚ heroes in reality do not have superhuman strength or the ability to kill giant beasts. They are usually people who help others and push towards a better future. These people would have qualities such as determination‚ humbleness‚ and selflessness. In the

AUTOMATIC WATER PUMP CONTROLLER The automatic water pump controller is used to control the water pump motor. The motor gets automatically switched on when water in the overhead tank (OHT) falls below the lower limit. Similarly‚ it gets switched off when the tank is filled up. Built around only one NAND gate IC (CD4011)‚ the circuit is simple‚ compact and economical. It works off a 12V DC power supply and consumes very little power. The circuit can be divided into two parts: controller circuit and

namely‚ pumps‚ fans‚ blowers and compressors. Though liquids particularly can be transported by operators carrying buckets‚ the usual mode of transport of fluids is through pipelines with pumps‚ compressors‚ fans and blowers. Generally‚ the word “pump” designates a machine or device for moving an incompressible liquid while fans‚ blowers and compressors are devices for moving gas (usually air). PUMPS There are three common types of pumps: the centrifugal pump‚ the reciprocating pump and the rotary

machinery problem. We intend to do a project on “Vibration analysis of centrifugal pump at BPCL Kochi Refinery”. The vibration analysis we have done is a part of predictive maintenance on rotary equipments. This technique is mainly used for the improved performance of equipments. Using this we can predict the condition of internal parts of the equipment. We are mainly dealing with the vibration analysis of centrifugal pump‚ compressors and motors. It includes typical causes of vibration like misalignment

referred to as “triple capacity” apparatus. This is because they can do three jobs. They can pump‚ transport personnel‚ and carry hose. It is possible to have a single function vehicle. For example‚ New York has had vehicles with giant pumps mounted on them. It can pump tens of thousands of gallons a minute. But that is all it can do. A separate vehicle‚ called a “Hose tender”‚ must be dispatched with the pump vehicle. It is also possible to have apparatus that can perform four or five major functions

used for pumping water. Wind pumps are windmills that are used in dry places for pumping underground water. The water is used to give clean drinking water‚ to water farms‚ producing salt from sea water‚ to remove extra water from floods‚ and for livestock. Wind pumps originate in the late 19th century. They were very important in economic development in part of the US. Wind pumps are often found in Argentina‚ South Africa‚ Asia‚ and the United States. A wind pump consists of a piston. A piston

Safe operation of GBC Check out while starting: • CW System: Ensure that the cooling water pump & at least 04/05 nos fan are in running condition. • Seal Gas Skid: Always Charge gas through gas filters GT-F8102 and fill the system. This prevents dirty gas going to seals. • Always maintain barrier seal pressure @ 0.3to 0.5 atg on OTB side and TB side before start of the Lube oil Pump and during normal operation. • Open the suction valve HIC 8001 only after the system is filled
