The heater design is made on certain assumptions being – (1) steady state rate of heat transfer (or that heat transfer rate is constant with time); (2) the cylindrical structure allows thermal symmetry so that the transfer of heat occurs merely on one dimension and varies not along the axial direction; (3) the metallic composition of the water tank (having thin metal sheet of stainless steel) on the inside possesses negligible thermal resistance; (4) thermal conductivities are uniform throughout the heating process; and that (5) very negligible heat losses take place on surfaces at the top and at the bottom.Among the available insulating materials in the market, the ‘foam’ is chosen for its affordability and low cost of installation. Compared to the other prospected insulators, its thermal conductivity appears to have given the most reasonable values for the length and surface area of the heater via R-equation, while others came out with lengths that converge to the value of the corresponding outer radius which is not likely in the actual. During the process of heating the water, every 500-W increment is dissipated through the insulated tank wall so the increase of power input ought to be compensated with the addition of foam with relative thickness so as to prevent unnecessary heat loss until the water has achieved the desired temperature at 65°C. Stainless steel is preferred to carbon steel or some other steel alloys due to the fact that it potentially resists corrosion over considerable time period.
This assignment "Process of heating the water" concerns the design of a heater. It is stated that the heater design is made on certain assumptions being – steady state rate of heat transfer (or that heat transfer rate is constant with time)…
There are extensive pressures on the nations to meet the water demands accordingly because of international conflicts, economic crisis, poverty, and water availability etc. PCA states that only 0.3 percent of total water is can be used for drinking purposes (PCA, 2005).Global issues stated from the report that 1.1 billion people in developing countries having inadequate access to water (Global issues, 2010).
Automatic control over various equipments could be achieved using modern computer technology. Communication technology extended the range of automated control endlessly.
The task to be completed is the design of an embedded distributed network system. The client hardware such as mobile phones or a Personal Digital Assistant (PDA), which is connected to mobile network, is to send and receive messages from a Personal Computer (PC) that is connected to the Internet.
According to the report the magnitude of the problem is increasing because of the lack of awareness among the general public of these areas about the sustainable and economical use of water. Qatar and a few solutions to the problem and methodologies for providing water are discussed. We have to save this resourse.
The objective of the experiment is to find out the specific heat capacity of water by monitoring change in temperature of a water that is heated to boiling under constant time interval.
The specific heat of any material determines the amount of energy needed to heat 1 kg of
Among the equipment which contain heat exchangers are; air conditioners, refrigerators, boilers and furnaces. These heat exchangers serve different purposes in different manufacturing industries. There are those
People understand heating water as the only method of making water safe for domestic consumption, sand filtration and straining were other methods they employ. At around 1500BC Ancient Egyptians came up with the idea of
largest cities unless states that tap the dwindling Colorado River find ways to reduce water consumption and deal with a crippling drought…” (Wines, 2014). It is also reported that the level of underground water is also decreasing: in 2009 it made 91 meters, while the index
