Specific heat capacity

involves discharging short puffs of air into the molten glass, known as gather, which is spooled at one end of the blowpipe. This causes the interior of the glass blob to form an elastic skin similar to that of the exterior caused to the decrease of heat emitted by the furnace. The glassblower can then rapidly inflate the molten glass to a comprehensible form and work it into required…

The Mpemba Effect The Mpemba effect is a rather unusual physical phenomenon where hot water freezes faster than cold water, under certain conditions. Intuitively, this doesn’t make any sense. How could water of higher temperature reach freezing temperature quicker than water of colder temperature? Water freezes when it’s molecules lose energy and slow down enough to stick together, forming ice. The molecules of water of high temperature have more energy the molecules in the colder water. So,…

sauna is a small room which is used to either get dry or wet heat sessions. These heat sessions can have great benefits on different aspects of your health. We will discuss here about some of the advantages gained from spending time in the heat. There are multiple benefits such as increasing endurance and improving muscles. First of all, it is important to understand that it is not easy to enjoy the benefits of a sauna. It produces serious heat and most people are not able to withstand it…

simplicity; where accurate and deep meanings have been considered which will also been elaborated in future sections. Briefly, the four Elements include the following components: Fire Air Water Soil a) Fire: comes with Heat and Dryness. It is the lightest of all Elements b) Air: comes with Heat and Moisture. It is heavier than fire, but lighter than water. c) Water: comes with Coldness and Moisture. It is heavier than Air, but lighter than Soil. d) Soil: comes with Coldness and Dryness. It is…

HOW JCB MACHINE WORKS The Basic Idea of Hydraulics: The basic idea behind any hydraulic system is very simple. Force that is applied at one point is transmitted to another point using an incompressible fluid. The fluid is almost always an oil of some sort. The force is almost always multiplied in the process. If two pistons fit into two glass cylinders fitted with oil and connected to one another with an oil-filled pipe. If you apply a downward force to one piston(suppose the left one), then…

2. The vapor-compression refrigeration cycle is the most broadly used cycle for refrigerators, air conditioning systems, and heat pumps. It consists of four processes: Process 1-2 Isentropic compression in a compressor. Process 2-3 Constant- pressure heat rejection in a condenser. Process 3-4 Throttling in an expansion device. Process 4-1 Constant –pressure heat absorption in an evaporator. In the ideal vapour-compression refrigeration cycle, the refrigerant enters as a saturated…

The experiment of fluidization in packed column was determined by using air as the conveying media. The fluidized bed is when the air make the solid to behave like a fluid. For this experiment, two columns are use which one column are filled with sand and the other one filled with aluminum oxide. The bed height of aluminum oxide is 100 mm and have a particle size about 250 micron (mesh 60). The minimum fluidization velocity is used to determine the pressure drop. As mentioned above, when the…

Description of the proposed heat release rate model. The cylinder gas is considered as a spatially homogeneous thermodynamic system occupying in a single zone for the compression, expansion, intake, exhaust processes and two zones (burned and unburned zone) for the combustion process. The instantaneous composition of cylinder gases are obtained from the mass fraction of fuel burned. The instantaneous thermodynamic properties are computed by the established equations [20-21, 28]. The…

The visual cell has a capacity of 100cc. The chamber is described as visual cell because it has a window that one can use to investigate phases or fluids. Furthermore, the visual cell has a gas or fluid of interest. The visual cell is designed in a way that it withstands high…

If your AC starts blowing hot air it may be due to the fact that it is freezing up. The coil is an important part of cooling your house up. The coils works by taking the warm air from your home and releasing them outside. If the coils in your AC unit become too cold they can freeze up. When your coils are frozen the ice can cause blockages, this results in you AC unit to run without cooling the home, whilst using a lot more electricity than usual. Why Do the Coils Continually Freeze Up? One…
