3.1.3 Pump
A pump is a gadget that moves liquids (fluids or gasses), or once in a while slurries, by mechanical activity. Pumps can be characterized into three noteworthy gatherings as indicated by the technique they use to move the liquid: direct lift, dislodging, and gravity pumps. Pumps work by some component (regularly responding or turning), and expend vitality to perform mechanical work by moving the liquid. Pumps work by means of numerous vitality sources, including manual operation, power, motors, or wind power, come in numerous sizes, from tiny for use in therapeutic applications to substantial mechanical pumps.

The water powered arm comprises of two chambers, one fitted into the other in a telescopic way. The width of the internal chamber is 14cm and its length is roughly 30cm. At the point when completely expanded the aggregate length of the two barrels is around 95.5cm. The prolongation and constriction of the internal barrel inside the external chamber gives the dish its development from east to west. The external surface of the inward barrel and the internal surface of the external chamber are isolated by an amazingly thin film of greasing up oil, which make the relative development of the two barrels smooth. An oil seal gave at the top end of the external barrel keeps the greasing up oil from spilling outside. The external chamber is secured to the tube shaped part of the vertical backing through an affixing gadget, which inflexibly holds the Superjack at an edge of around 45o with respect to the vertical backing. The Superjack is associated with the body of the illustrative dish through an opening on a bit of metal at the highest point of the internal barrel. The operation of the following system can be controlled either physically or naturally. For both methods of control, an electric circuit must be produced. In this manner when the switch is turned in one bearing, the control of the dish is programmed, utilizing the two sunlight based sensors. At the point when the switch is turned the other way, the control of the dish is manual.

3.1.5 Valves
A valve is a gadget that manages, coordinates or controls the stream of a liquid (gasses, fluids, fluidized solids, or slurries) by opening, shutting, or somewhat discouraging different paths. Valves are actually fittings, however are normally examined as a different class. In an open valve, liquid streams in a course from higher weight to lower

    There are three main types of HPLC pumps which are constant flow reciprocating pump or pistol type pump, pneumatic pump and syringe type. The constant flow reciprocating pump, also known as pistol pump is commonly used in the HPLC instrument due to the constant generation of pressure and can use for both isocratic and gradient pump. There are two types of the ways to operate the pump which are isocratic pump and gradient pump. The isocratic pump is used to move the constant mobile phase configuration and the gradient pump is used to move the variable mobile phase contents and increase the composition of mobile phase. The gradient pump needs dual pump but the isocratic is only needed for single pump.…

    THEORY: The Venturi flow meter is an equipment that uses the Bernoulli Effect and a manometer pressure gauge to measure the rate of flow of a liquid or fluid that is flowing through a pipe. There is also a part in the venture equipment that has a reduced cross-sectional area. When the liquid goes through this part, the speed (velocity) tend to…

    There are several methods for measuring pH. The most common is the use of a glass electrode sensible to it, a reference electrode and a measurement device. Another method is the use of indicators and colorimeters. Indicators are materials specifically designed to change color when they are exposed to different pH levels. The colorimeter is a device that utilizes a container filled with a determined volume of sample to which a reactive is added.…

    This makes the liquid boil at a lower temperature. Figure 5 DIstillation under Reduced Pressure STEAM DISTILLATION Steam distillation is a special type of distillation used for temperature sensitive materials like natural aromatic compounds which are insoluble in water, but volatile in steam. The non-volatile impurities are left behind in the flask. It once was a popular laboratory method for purification of organic compounds, but has become obsolete by vacuum distillation. Figure 6 Steam Distillation EXTRACTION WITH A SOLVENT The process of removing or separating a substance from its aqueous solution using a suitable organic solvent is called extraction.…

    Ref. 2 shows, however, that perforating the plate can prevent the formation of a bul~ble, and hence suppress the regular shedding of eddies and much of the random low-frequency velocity fluctuation. 6. Comlusio~s.--The effects of aspect ratio on drag, base pressure and flow pattern are small up to A --=- 10. All the plates shed turbulent eddies at particular frequencies; generally there are two shedding frequencies for each rectangular plate, one associated with the smaller dimension of the plate and a lower frequency associated with the longer dimension.…

    The purpose of this stage is mixing the generated Isobutylene that comes from the Oleflex unit with the excess amount of methanol manufactured by QAFAC to produce MTBE. Two isobutylene spheres (V 3101, V 3102) are designed to store 2,400 m3 other than storing requirements. These spheres can receive isobutylene after shutdown in the downstream and they are continuously charge and receive Isobutylene in initial startup and normal shutdown. The feed passes through highly acidic ion exchange (V 2302), low temperature and relatively high pressure, these conditions are required to mix Isobutylene with methanol to produce MTBE. MX 2301 is the Mixer in this stage of the process that mixes isobutylene that comes from (V 3101, V 3102) with Methanol from Methanol drum (V 2303).…
