What is an Onsen? An onsen is a term used for Japanese people referring to the “hot spring baths”. A natural Onsen use hot water from geothermal heated springs, though there are many indoor onsen (bath houses) that are filled with heated tap water. The onsens were used as public baths for Japanese people but nowadays there are many private ones and it’s also a tourist attraction for foreigners. My experience I went to one onsen in Nagoya called “Ozone No Yu”. Ozone-Cho, Higashi-ku Nagoya…

An air conditioner is very essential to both homes and businesses. You will note that this device normally helps to either warm or cool the temperatures of your house. During summer, the temperatures can be very hot. This can make you feel uncomfortable. In this case, you need an air conditioner in order to regulate the temperatures of your house. During winter, the temperatures can get very low. This can be detrimental. You need to warm up the temperatures of your house so that you can feel…

1. Temperature : A temperature is an objective measurement of hot or cold. It is measured by thermometer (Paul S. Welch,1938). Its most common unit is celcius. It is an important physical property of water because temperature controls the rate of most of the chemical reaction. As temperature affects the growth, reproduction and immunity of living organisms, therefore, drastic temperature changes can be fatal to living organisms. 2. pH : pH is a numeric scale used to specify the acidity or…

Thermosel Stainless Steel Bellow Expansion Joint was designed to utilize the piping system and to monitor the thermal expansion or terminal movement where the utilization of extension circles is undesirable or unreasonable. We offer this Thermosel Stainless Steel Bellow Expansion Joint that can prevent the unnecessary damage caused by vibration, pressure thrust, thermal growth, and other mechanical issues that can affect to the piping system. These Expansion joints are uniquely intended to…

thermocouple in Example 5. 1 (b) Thermal resistance network model Heat loss from the thermocouple is modeled as shown above by discussion leading to Equation 5.3. Thermocouple attached to the surface of a massive solid whose temperature we would like to measure. Excepting where the thermocouple has been attached the rest of the surface of the solid is assumed to be perfectly insulated. Since the thermocouple conducts away some heat from the solid there is a depression of temperature of the…

The heat exchanger design is an optimization engineering problem, to approach the best solution for sizing and selection of a heat exchanger and also to analyze its thermal performance. A properly sized heat exchanger should incorporate excess capacity to account for fouling that will occur during operation but too much oversizing results in higher manufacturing and installation costs. The most appropriate metric to describe the performance of a heat exchanger is its thermal capacity, which is…

experiment was to determine the thermodynamic properties of the entropy, enthalpy and free energy, as well as the solubility product of borax as a function of temperature from the dissolution of borax in an aqueous solution. Thermodynamics is the study of heat and its transformations. The properties of thermodynamics are entropy, enthalpy and free energy. The properties of thermodynamics can be viewed in terms of spontaneity. Spontaneity is a spontaneous change of a system that occurs by itself…

The goal of this lab was to determine the heat of fusion of ice (or water). According to Chem.Libretexts.org, Heat of fusion is where solids are heated to a specific heat capacity (The number of heat units needed 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…

There are three main heat transmitters, they are conduction, convection and radiation. Conduction of heat occurs when molecules increase in kinetic energy, the molecules vibrate and this vibration passes the heat to the surrounding molecules. Conduction only occur in solids. Convection is a type of heat transfer that only occurs with liquids and gases because it involves the liquids and gases physically moving, which a solid is unable to do. Convection happens when there is a difference in…

3 Ways To Boost Furnace Effectiveness When the warm air inside your house leaks out quickly, your furnace will have to work harder than normal to keep your home warm. Having walls, ceilings, and floors that are properly insulated will go a long way with keeping the hot air in, but they are not enough. Windows are one area where air tends to leak out the most, and if you ignore them, your furnace won’t be operating at optimal efficiency. Double-Pane Windows If your home is older and still has…
