Outcome 3 explores what it takes for a writer to produce complex, analytical, persuasive arguments that contribute to the conversation of existing research and matter in academic contexts. It is important for a writer, when developing a complex and analytical claim, to implement the stakes of the argument, and why the argument matters to their field of research. If the argument has no purpose, then the writers desired audience have no reason to read it. It is also vital for the writer to…
Defining the Problem/Question
Task 2 was to create a proposal to determine the quantitative characteristics that could control the light that is emitted from glow sticks. For task 3 the problem was to find one or more trends that could quantitatively control the amount of light emitted from the glow sticks. This investigation has value to companies or people that want to find a way to increase the brightness of glow sticks.
Experimental Design and Procedure
To control the amount of light…
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…
thermocouple in Example 5. 1 (b) Thermal resistance
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…
maybe, but incorrect! "Hot air" rises but "heat" can travel in any direction. That is why you can feel the heat of the cup when you place your hand to the side of it. Radiant energy transfer is caused by a warm surface giving up its heat to a cooler surface. Whenever there is a temperature difference between two surfaces, both surfaces will attempt to equalize. Radiant energy travels through space without heating the space itself. It only turns into heat when it contacts a cooler surface. Our…
DIMENSION ALONG A SINGLE BAR
Fourier’s Law of Heat Conduction:
It states that,
“Flow of heat per unit is proportional to the temperature difference per unit length.”
By re-writing above relation,
dx/kA=Conductive Resistance of the material
Properties of “K”:
It is a material property and a function of temperature.
It may be different in different orientations.

container. After that I put a layer of aluminum foil on the bubble wrap and then put cotton balls and extra styrofoam on top of the foil. The last thing I did was put duct tape on all of the cracks in the cardboard box.
Conduction is a method of heat transfer, it can only be transferred through direct contact. To minimize conduction I used duct tape to hold down the ice container. In this lab I tried to use a lot of insulators…

minimizing heat loss via the mechanisms of conduction, convection and radiation. The thermos design must be freestanding and effective against any means of heat loss to the surroundings. This data is then compared to a control, which is a cup of hot water in a polystyrene cup without any sort of insulation and protection against heat transfer to determine the effectiveness of the thermos in regards to heat loss via conduction, convection and radiation.
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…
