I will pay for the following article ContinuousStirred Tank Reactors. The work is to be 8 pages with three to five sources, with in-text citations and a reference page. In this experiment, no chemical reaction takes place. The residence time behavior of a dissolved salt through a cascade of three continuous stirred tanks is examined at different flowrates for a constant starting concentration of salt. The experimentally determined variation of slat concentration with time in each tank is compared with results predicted from theoretical equations, allowing deviations from ideal behavior to be observed. Conversion of reactant is then estimated by graphical integration for both the experimental results and theoretical data. The general effects of the transient concentration of reactants are similar to those induced in a chemical reactor, subject to variation in throughput.

1. Three equal-sized Perspex tanks with provision for overflow from tank 1 to tank 2 then to tank 3, and for the overflow from the drain. Each tank measures 152mm by 254mm deep with the overflow weirs being placed 228mm from the base. The tanks are stirred by propellers driven by the same drive motor. A rotameter controls the feed to tank 1.

2. A portable conductivity meter is available to measure the conductivity of the solution in each tank. It has four scales, which can be adjusted to give a reading in the desired range. For dilute solutions, conductivity is approximately proportional to salt concentration. The units on the meter must be checked.

1. Fill the tanks with cold water directly from the tap initially, and then through the rotameter unit all tanks are full and flowing freely down the cascade. Stop the water flow and remove half of the water from the first tank. Place 50g of sodium chloride in a 500ml beaker, add some cold water and stir with a glass rod to dissolve the salt. Pour the solution into the first tank and start the stirrers to mix completely.

2. Start the water flow at 1.0 liter per min into the first tank using the rotameter (range 0.2 to 3.4 L/min). The water levels in each tank will automatically adjust until the flow in&nbsp.and out of each tank is the same.

3. The test starts when the water starts to overflow from tank 1 to tank 2. Start the clock at this point and take conductivity readings in each tank at various time intervals, e.g. every 1 or 2 minutes, so that graphs of conductivity in each tank can be drawn as a function of time. The solution conductivity is measured by dipping the probe into the tank and allowing a few seconds before taking a reading. It is not necessary to wash the probe between readings. Also, it is not necessary to sample all tanks at exactly the same time provided that the correct time is recorded for each reading.

Hello, I am looking for someone to write an article on Concentrating Sunlight with Fiber Optics AKA Hybrid Solar Lighting. It needs to be at least 3500 words. Since the price and ease of electrical illumination sources were very high, the awareness of installing the light source anywhere in the building was not implemented. Also, the disadvantages of the system which include the difficulty of control, variability, and excessive illuminance were exposed (Beshears 55).

The sunshine guidance technologies based on extremely efficient optic material have enhanced the direction of sunshine into the interior of the building that normal glazing cannot reach. The daylight interiors have beneficial effects on the well being, and also, energy conservation is permitted by the use of daylight as an alternative source of lighting interior buildings. The optical materials have been used to direct daylight in an efficient way into any part of story buildings.

TDGS is the most significant light technology which has succeeded. TDGS technology has been in use for the last nine or more years in most parts of the world with various applications. Many studies have done in light delivery methods can be used to provide comfortable and economical interior building conditions and TDGS integration with electrical lighting using various technologies.

Current technologies that combine the delivery of electrical light and sunshine into the same place have been HLS. The technology moves daylight into the interior of the building where it combines with electrical light in the systems that are equipped with various controls to increase the use of available daylight. The only setback of this system is that there has been none or few post-installation studies published, and there is little information on the design methods the performance criteria of the system in use. (Mayhoub and Carter 267)

In this technology of Hybrid Lighting Systems (HLS), daylight is combined with electrical light before delivery. Organizing of optics is more similar to artificial light and hence they may not look different. The author of the table has also included the estimates of system efficiencies for certain story applications. Information on individual components’ efficiency and size are represented in the table.
