Introduction: In industry‚ a heat exchanger is used to cool down streams for temperature sensitive processes. The now hot cooling water is useless to the plant unless something is done to cool it down. In industry‚ cooling water towers are used to bring the water back down to a sufficient level . In a cooling tower‚ outside atmospheric air is flowed through a “column” while the hot water sprayed into the system. Since air is never at full saturation of water (unless it is raining)‚ some of the hot

Strontium Manganese Oxide Introduction The ternary inter oxide SrMnO3 was first characterized by XRD by Negas and Roth []. This perovskite type inter oxide crystallizes in the hexagonal form with the space group P63/mmC(194). This inter oxide is of considerable interest to materials scientists owing to its ability to accommodate a high degree of anion vacancies‚ crystal structure and its high Neel Temperature (TN). It also exhibits polymorphism with two different cubic and hexagonal structures

Micropower Energy Harvesting Abstract More than a decade of research in the field of thermal‚ motion‚ vibration and electromagnetic radiation energy harvesting has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC–DC conversion are becoming able to efficiently convert the power from these energy harvesters. This paper summarizes recent energy harvesting results. Introduction The low power consumption of silicon-based electronics

Thermodynamic Investigation of the Joule-Thompson Effect and Coefficient Determination for Helium and Carbon Dioxide Niki Spadaro‚ Megan Cheney‚ and Jake Lambeth University of North Florida‚ CHM4410C Fall 2010 The Joule-Thomson coefficient explains the behavior of any real gas when changes in intensive properties‚ such as temperature and pressure‚ occur. The coefficients for helium and carbon dioxide were determined using a Joule-Thomson apparatus that created constant enthalpy within the

Linear Variable Displacement Transducer (LVDT): A very basic transducer which is always useful in the field of instrumentation‚ I have studied about this in my college days. Now let me explain about the LVDT with its Principle of Operation and I will explain how it is constructed for its well known operation and you can understand the working of LVDT. Principle of LVDT: LVDT works under the principle of mutual induction‚ and the displacement which is a non-electrical energy is converted into an

Experiment M4 : 2 Stroke‚ 4 Stroke Diesel Engines Abstract Introduction The aim of this experiment was to explore the engines testing methods and to find how the chemical energy in the fuel is converted into power and distributed throughout the system. Six major components of the engine were studied to understand their effect on the engine. Also‚ a multi-cylinder diesel engine is tested for its efficiency. Development of efficiency of the engine has allowed the motor companies to grow very rapidly

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

Writing Exercise Crystallochemical relationship is one whereby the main structural features act as exhaustive aspects on the similar basis as the closely-related composition of chemicals. It is extremely important to have an understanding of the crystallochemical relationship between structures and temperature as having knowledge of it leads to a perfection in the structures formation. This is especially so as the structural parameters of FePO4 falls very closely to the values that are limited i
