Abstract
Solar still is very important device to convert the available brackish water into drinkable water. Here work is carried out to know the effect of coupling an Evacuated Heat Pipe Collector on the solar still. Other different parameters like Water depth, Sun direction and solar radiation to enhance the productivity. It has found that coupling an Evacuated Heat pipe collector with a solar still has increased the productivity by 32%. Also it has found that the productivity is reduced while using higher water depth and solar insolation is directly proportional to the Productivity.

Keywords: Pyranometer, Thermocouples, Evacuated Heat Pipe Collector

1. Introduction
O.O. Badran [1] performed experiment on single slope solar still using different operational parameters like basin water depth, glass cover thickness, insulating materials and proved that, productivity of distilled output is increased upto 51% when combined enhancers such as asphalt basin liner and sprinkler have been applied on single slope solar still.Kalidasa Murugavel et.al.[2] gave brief report on solar desalination regarding with various methods of improving the productivity. They suggested that different materials are used in basin solar still to improve the heat capacity, radiation absorption capacity and condensation rate. Kalidasa Murugavel at.al [3] used different wick materials like light cotton cloth, light jute cloth, sponge sheet of 2 mm thickness and different porous

    Background: Distillation consists of heating a liquid until it vaporizes, and then condensing the vapor and collecting it in a separate container. Distillation is used to separate mixtures of liquids that either have different boiling points, or that have one component that does not distill. There are many types of distillation, each of which has a distinct purpose. Steam distillation is used to isolate volatile substances that have high boiling points. When two immiscible liquids are distilled together, the amounts of each component in the distillate are constant. Also, the boiling point of the mixture is lower than that of either of the individual components. This is because the components do not have compatible intermolecular forces, and so the component in lesser concentration will form “bubbles”, like oil droplets in water, weakening the overall intermolecular forces in the mixture, and thus lowering the boiling point. This process allows high- boiling compounds, which can decompose before they boil if heated alone, to be distilled at temperatures below 100°C. Once the liquid mixture is heated to its boiling point, the liquid is converted to vapor. The vapors, richer in a more volatile component, are then condensed into a separate container.…

    The lab for this paper was conducted for the topic of osmosis, the movement of water from high to low concentration. Five artificial cells were created, each being filled with different concentrated solutions of sucrose. These artificial cells were placed in hypertonic, hypotonic, or isotonic solutions for a period of 90 min. Over time, the rate of osmosis was measured by calculating the weight of each artificial cell on given intervals (every 10 minutes). The resulting weights were recorded and the data was graphed. We then could draw conclusions on the lab.…

    To begin this experiment a water bath was assembled using a 100 mL beaker, and filling it half way with cool tap water. Then, crushed ice was placed in the remainder of the beaker just below the top. Salt was finally added to the beaker and the solution was stirred well. After, a test tube was filled with distilled water, and the temperature was recorded every 30 seconds until the temperature reading was steady for five consecutive 30…

    Active solar heating is a system of putting the sun's energy to use in which collectors absorb solar energy and pumps or fans distribute the collected heat. This functions in the manner that heat absorbed by a solar collector is transferred to a fluid inside the panel, which is then pumped to the heat exchanger, where the heat is transferred to water that will be stored in the hot water tank.…

    The east of Egypt is bordered by the Red Sea making the option of desalination possible; however, the costs and adverse effects on the environment make it unappealing. A second option to be considered is water recycling. This option is cheaper and it also has a lower adverse effect on the environment. This report will analyze both desalination and water recycling techniques, based on cost, effects on the environment and social acceptance.…
