Thermodynamic temperature

Surface and center temperature of the mushroom, ambient humidity and temperature of vacuum chamber have been measured and recorded by the data logger inside the vacuum chamber (see Fig. 1). On the other hand, the control unit that records the pressure data is located outside the vacuum chamber (see Fig. 1). The measured data saved for each 10 seconds. Before starting the cooling, vacuum pump runs half an hour for stabilizing the system. Experiments carried out for three replicates and the…

present study was made to evaluate the performance of Braysson cycle. Braysson cycle is a hybrid gas turbine, combination of Brayton cycle and Ericsson cycle. The hybrid gas turbine is proposed based on the Brayton cycle at high temperature heat addition and low temperature heat rejection at Ericsson cycle. The performance was evaluated in terms of thermal efficiency, exergy losses and specific power output. Energy and exergy analysis was carried out on Braysson cycle and Brayton cycle. The…

Unfortunately, 1 kg of hydrogen requires 11 m3 of volume at ambient temperature and pressure. In addition, a load between 4 and 8 kg is required to guarantee comparable driving ranges with petrol fuelled cars. It is obvious that ways have to be found to increase hydrogen density to a level where storage mobility is feasible…

insert and remove the biscuit and hold the biscuit in place so when the oven is tilled to get direct sunlight, the biscuit does not slide. To measure the temperature inside the inside cooking chamber, there must be a hole in one of the inside chamber walls to insert a digital thermometer. Thermometer CANNOT be place through the…

β-FePO4. One of the observed differences is that when the quartz is present at different temperatures. The α-FePO4 phase when present at low temperatures, tend towards the values obtained for β-FePO4 at high temperature. In addition, this case is true for all α quartz when at low temperature, in that it will tend to the values obtained for its respective β quartz experienced at high temperature. When the temperature of a system approach 980 Kelvin, the Fe-O-P bridging angles subsequently rise…

to raise the temperature by 1 degrees) in order to break the bonds that are keeping them attached, which is called the attractive force. This lab also dealt with the concept of the direction in which a temperature follow. According to chemistryexplained.com, temperature is the measure of how hot or cold something is or the amount of kinetic energy an object has. Furthermore, temperature is the flow of energy from high to low. In this experiment, the water started with a high temperature meaning…

distance that was applied to the object. In the end energy is the measurement of the possibility of an object working on another object. With knowing how energy works, it is possible to understand the Laws of Thermodynamics and how they relate to heat transfer. Within the Laws of Thermodynamics there are three ways that heat can be transferred. These ways are convection, conduction, and finally radiation. Convection deals with liquid heat transfers. Convections currents are used typically with…

of the mechanical fields such as stress, strain and displacement with temperature field and investigates the interaction on the basis of the thermodynamics of the irreversible processes. It relates two separate and independently developed sciences: the theory of elasticity and the theory of heat conduction. The two basic branches of elasticity, namely elastostatic and elastodynamics are developed under different thermodynamic assumptions. The problems of static are regarded as isothermal and…

Abstract In this study equilibrium isotherms, kinetics and thermodynamics of ciprofloxacin on seven sediments in a batch sorption process were examined. The effects of contact time, initial ciprofloxacin concentration, temperature and ionic strength on the sorption process were studied. The Kd parameter from Linear sorption model was determined by linear regression analysis, while the Freundlich and Dubinin–Radushkevich (D–R) sorption models were applied to describe the equilibrium isotherms by…

2.2. Instrumentation The residual concentration of metal ion in the filtrate were analyzed by GBC, Sensaa Series Atomic Absorption Spectrometry (computerized AAS) with air-acetylene flame under the optimum instrumental conditions as shown in (Table 1). The solution pH was measured using digital pH meter (Hanna instrument model HI 8519, Italy). Fourier transform infrared (FT-IR) spectra were measured on Nicolet is 10 FTIR spectrometer in the range of (4000 to 400 cm-1). Scanning electron…
