Magnetoresistive (MR) sensors to sense the position of a magnet attached to the moving object. The system also has the ability to monitor the ambient operating temperature and detect if it is exposed to an external disturbing magnetic field. Several other components such as the differential amplifier‚ a band-pass filter and a temperature compensation circuit are used to process sensors signal and compensate the errors. The system offers a high resolution of 0.00616 mm‚ a bandwidth of 9 KHz and a

have to check that the sum of the temperature is equal. * Then cover one of the plastic jar with its lid. * Place both jars in front of the lamp in the equal distance * Record the temperatures of the two thermometers every ½ hour that was place inside the jars. At the beginning of this temperature record‚ the measurement errors occur in this result of the experiment. Like that the temperature of the jar without lid was higher than the temperature of the jar with lid. The mistake I

The calorimeter containing the 50gm of water was set on the cork mat and its temperature recorded at 23o C. * The other calorimeter containing 100gm of water was placed on the tripod and the Bunsen burner lit. * The thermometer was placed into the calorimeter and the water heated to approximately 73oC. then removed from the heat and stirred until a temperature of 70o C was achieved. * When this temperature was achieved‚ the water in this calorimeter (B) was poured into the calorimeter

cloud cover‚ the angle of the sun‚ the particle matter in the air and the surface area (Lutgens‚ Tarbuck‚ Tasa‚ 2011).Thus a higher albedo indicates a surface that absorbs less heat‚ and remains cooler. There are several factors that cause higher temperatures in urban area like dark rooftops‚ dark asphalt surfaces‚ and more buildings with more emitted heat from air conditioners and furnaces and denser traffic which cause elevated emissions of air pollutants. Dark roofs and dark asphalt surfaces have

performance measurements of a prototype thermoelectric generator mounted on self-ignition (Diesel) engine. Using the prototype generator as a tool‚ benchmark studies were performed for improvements in the heat exchanger including determination of temperature distribution and heat flux density. Introduction Contemporary car engines exchange app. 30-40% of heat generated in the process of fuel combustion into useful mechanical work. The remaining heat is emitted to the environment through the exhaust

variable of enthalpy‚ ∆H for the dissolution reaction of boric acid in water. The solubility of boric acid was measured over a range of various temperatures by finding out at what temperature crystallization began for solution of different molarities. A graphical relationship between the natural logarithm of molal concentration and the inverse of the temperature gave a linear plot to determine the enthalpy changes associated with the reaction. Methodology: The procedure was carried out as follows in

The amount of heat and moisture are gained from the building internal and external heat sources that is required to be removed by the building cooling system. Both heating and cooling loads form the basis in designing the HVAC systems for the building and occupied spaces to achieve both

engine takes heat from a high temperature reservoir‚ converts some to useful work and rejects the remainder to the low temp reservoir. - Second law of thermodynamics - It is impossible for heat to flow spontaneously from a cooler body to a hotter body - No heat engine operating in a cycle can concert all thermal energy into work. (100% thermal efficiency is impossible) - Third law of thermodynamics - It is impossible to attain a temperature of absolute zero - Absolute

electromagnetic radiation emitted by objects is affected by the object’s temperature. In this simulation‚ you can input the temperature and observe the spectrum of the radiation emitted. a) The temperature of stars in the universe varies with the type of star and the age of the star among other things. By looking at the shape of the spectrum of light emitted by a star‚ we can tell something about its average surface temperature. i) If we observe a star’s spectrum and find that the peak power occurs
