The other readings remain the same. Blow it out so it is smoking and glowing red. This article along with a copy of an article that a student "talked to the text" on is included.

Set the apparatus up for counter flow as seen on the apparatus panel and repeat the other steps from 2. It is important that you write down what happened differently with each light source. This solid domain is then coupled with computational fluid dynamics to solve for the heat transfer and fluid flow behavior.

In this experiment heat transfer from the extended surface relies on natural convection and radiation. The temperature of the bar is measured at different sections.

Students must wear safety gloves to handle the hot water containers. To start the heat exchanger turn on the power switch and set the temperature controller to the desired temperature oC. Pay careful attention and make observations. The heat input to the heater is measured by a ammeter and a Voltmeter and is varied by a variac.

This is convection in action. The apparatus consists of a cylindrical glass container housing the test heater ad a hater coil for the initial heating of the water.

The heater inputs to the two plates are dissipated by conduction, convection and radiation. You can purchase a conduction apparatus here.

Heat input to the heater is given through variac.

This will ruin the candle below if the matches get caught in the wax. In order to ensure an equal rate of heat flow from both sides of the heating element, the heating element is sandwiched between two identical sets of composite slabs. Students must wear goggles while performing this task.

The temperature setting is adjusted at the thermostat on the front panel. To compare at the pore scale, we use discrete element method DEM models to generate numerical packed beds. When students fold the touch paper "hot dog" style and put it in the tube, some students want to "shove" it all the way in the tube and let go.

Observe what occurs and record your observations on the lab sheet. Do this for both of the valves. The slab materials are Cast iron, Bakelite and press wood. Here is a quick modeling session I did with my kids with this article. You can purchase a radiometer here. The method of experiment is allowing solid shapes of different sizes, form and materials of construction to stabilise at room temperature and then dropped into a bath of hot water.

There is provision of illuminating the test heater wire with help of a lamp projecting light from behind the container. A heater heats one end of fin and heat flows to another end. Since each material has different thermal conductivity, heat transferred through each of them is different.

In a previous lessonstudents "talked to the text" to identify some textual evidence of heat transfer. This study is under NSF Award Make a hypothesis as to which bead will fall off the spoon first. Each flow arrangement is shown on a diagram located on the front panel.

I tell the students that they may not pick it up off the lab table. Once the water is heated to the desired temperature it is transferred by a water pump next to the tank.
