Experimental study of the effect of primary nozzle position on the performance of jet ejector

In this work the effect of primary nozzle positions relative to the mixing section in an ejector on the performance of the air ejector are investigated. Air jet ejector and four types of nozzles are designed and constructed. Two nozzles are circular and the other two are squared. Then an apparatus is designed and constructed to achieve the ejector performance (enhancing the entrainment ratio). Due to the rapid decreasing of air flow rate coming from air reservoir of the compressor to the ejector, a data acquisition system is used to record different measurements such as pressure, temperature and velocity at different locations on the test apparatus. The convergent nozzle can be moved to study the effect of nozzle positions on the ejector performance. Tests are carried out at three different positions for each nozzle, the distance between it was equal. At the 1st position, the exit section of the primary nozzle is located just at the inlet plane of the mixing section of the ejector. At the 2nd position, the exit section of the primary nozzle is shifted 8.5 mm before the inlet plane of the mixing section. For the 3rd position, the exit section of the primary nozzle is shifted 17 mm before the inlet plane of the mixing section. From detailed analysis of experimental results, it is found that: The performance of the ejector is affected by the nozzle position, and the optimum position which achieves a maximum entrainment ratio for all nozzles is at position (1), (nearest position to mixing section of the ejector. But the entrainment ratio increases when the nozzle is placed at position (2) in case of the small squared nozzle. Position (3) is the worst position for all nozzle and achieves minimum entrainment ratio. Regardless the position of the primary nozzle, there is a strong relation between the nozzle exit area and the performance of the ejector, i.e. decreasing of primary nozzle exit area increases ejector entrainment ratio.

Project Progress Monitoring Service Using Geospatial Server

The success of a project depends on efficient project monitoring. projects span across long duration and need that the same tasks be performed again and again over a number of brief segments to complete the job. Monitoring their development so becomes difficult. This is a matter of concern meanwhile Monitoring the project's development regularly can help ensure that resources are used and distributed effectively. The current methods of monitoring are either time-consuming, expensive, or necessitate a lot of human efforts. The study's goal is to examine the potential of using ArcGIS Pro to gather and visualize data for improved progress monitoring of linear projects. It also aims to make it possible for users - both operators and clients - to check the status of their projects online through dashboards and use as an operational tool for running their organization efficiently.

Hydrosol and essential oils are extracted from it and utilised as medicine. It is a medicinal plant with a Murakkabul Quwa temperament that is commonly cultivated throughout India. For therapeutic purpose, dried petals are utilised. It has several cosmetic benefits like it acts as natural moisturizer, has soothing effect, tones uneven skin and boosts collagen production as it is rich in vitamin c. In addition to this it is used as a Mullayin (Laxative), Muqawwi-e-Badan (General tonic), Mufarreh (Exhilarant), etc… Ibn Baitar has mentioned about the advantages of Arq-e-Gulaab (Rose water) on brain. This review article addresses the therapeutic applications and medical effectiveness of Gul-e-Surkh.

Removal of turbidity and total dissolved solids by using natural and artificial coagulants

Turbidity is the measure of the relative clarity of a liquid. It is an optical characteristic of water and is a measurement of the amount of light that is scattered by material in the water when a light is shined through the water sample. The higher the intensity of scattered light, the higher the turbidity. Turbidity in the water creates both aesthetic and health issues. Surface water treatment plants remove particles because they can cause objectionable appearances, tastes, and odours and can interfere with disinfection. A wide range of natural coagulants, such as moringa seeds, banana peel, jatropha curcas, cassava peel starch, watermelon, pawpaw, beans, nirmali seeds, and okra have been studied previously. Natural coagulants in powder forms are usually added directly to wastewater. The most commonly used inorganic chemical coagulants in water treatment. Aluminium sulfate Al2(SO4)3 is the most commonly used chemical for coagulation in wastewater treatment. Additional commonly used coagulants include sodium aluminate NaAlO₂, ferric sulphate Fe2(SO4)3, and ferric chloride FeCl3. Wastewater can be destructive for the public because it contains a variety of organic and inorganic substances, biological substances, toxic inorganic compounds, and the presence of toxic materials. The coagulant chemicals and their associated products are resourceful but these may change the characteristics of water. The wastewater can be harmful for local uses, so we are going to treat this wastewater by removing turbidity and total dissolved solids by using natural & artificial coagulants. In this process, the wastewater will be treated for other uses like in construction for mixing with cement or curing and other works.
