Essay on Heat Stroke

from nothing. Energy exists and cannot become nonexistent and nonexistent energy cannot become exist. The first law makes use of the key concepts of internal energy, heat, and system work. It is used extensively in the discussion of heat engines.  Example: An example of first law of thermodynamics is when a fan is on, the motor heats up;…

What Is Slate Shingle Metal Roofing And Why Is It Better Than Slate Stone Tiles? Slate shingle metal roofing is a roofing material made from metal and stamped to mimic the appearance of natural slate stone. A slate stone roof adds a touch of luxury to your home, but there are a few reasons why the metal version is superior. If you love the look of slate, you may want to look into slate shingle metal roofing. Here are a few reasons why. Metal Slate Tiles Are Much Lighter Than Stone One reason…

Air Fryer and Convection Oven Although they seem to be almost identical, there’s a difference between air fryer and convection oven. At first sight, they seem to be doing the same job. The air circulation provides the food with the needed amount of heat for even cooking. The hot air circulation principle requires little to no oil for food preparation. However, there are certain differences which can help you make up your mind. These details can determine your decisions when it comes to your new…

negative change in enthalpy. Since the energy released is usually heat, keeping track of the heat flow in reactions will help determine the change in enthalpy of a reaction. Observing the measurement of heat changes is known as calorimetry; hence, in this lab a calorimeter was used to measure the changes in enthalpy. A calorimeter is well-designed when it is well insulated from the environment so there could be minimal to no heat change between the system and…

Basic concept of Qi Qi (氣), in Chinese, refers to all gaseous substances that make up the universe. Externally, it forms the air and gases in the atmosphere. Internally, Qi is regarded as the energy stored in human body. The concept of Qi can be traced back to the Ancient Chinese Philosophy, in which people held the belief that Qi is the fundamental life force of everything; it forms all matters in the universe and ranges from external environment to the internal energy stored inside the body.…

The above graph shows temperature of Sn0.3Ag0.7Cux In alloy as a function of indi-um weight percentage. Initially with no traces of Indium, the solidus temperature & liquidus temperature are 219.40̊C and 241.70̊C. It clearly shows that the temperature range goes wider as the concentration of indium is increased [6]. This is not a cost effective solution as indium is very costly. Titanium oxide nano particles addition led to temperature changing from 217 to 217.64 degree Celsius [7]. Zinc oxide…

This project consist of Numerical and Computational Fluid dynamics analysis of heat transfer enhancement and the corresponding pressure drop over a flat surface equipped with cylindrical cross-sectional perforated and solid pin fins in a rectangular channel. The channel had a cross-sectional area of 250-100 mm2. The experiments covered the following range: Reynolds number 13,500–43,500, the constant clearance ratio (C/H) = 0, the inter-fin spacing ratio (Sy/D) 1.944 and 3.417 for Staggered…

growls we hear in storms truly start from the speedy improvement of the air enveloping the lightning jar. As lightning partner with the ground from the fogs, a second stroke of lightning will return from the earliest starting point the fogs, after the same channel as the first strike. The hotness from the force of this return stroke raises the temperature of the incorporating air to around 27,000 C° (48,632 F°). Since the lightning takes so little time to go from point A to point B, the warmed…

Abstract:The second order rotatory theory of hydrodynamic lubrication was founded on the expression obtained by retaining the terms containing first and second powers of rotation number in the extended generalized Reynolds equation. In the present paper, there are some new excellent fundamental solutions with the help of geometrical figures, expressions, calculated tables and graphs for the porous bearings in the second order rotatory theory of hydrodynamic lubrication. The analysis of equations…
