Heat transfer principles and applications

Arrangement and Composition of Fuels Present in Each Office Cubicle

According to the slide show, the two-sided workstation contains a variety of what is known as organic fuels. Visible objects that can be acknowledged as fuel include the cubicle walls or the partition of the workstation encapsulating the interior in a "L" shape formation, this appear to be made of medium to high density material most likely plastic and wood. The cubicle has a single shelf running on one side of the workstation and on it are files that appear to have papers in them. Running parallel below the shelf is a desk. The desk appears to be made of the same material as the walls. On the desk, there is a cathode computer screen. Alongside the screen is a collection of files and books others lying on top of the desk and other placed upright next to the screen. There is a computer keyboard attached to the screen at the base. Back of the desk is a seat made of plastic, cloth, foam and metal. Under the desk, there are two piles of about two feet each of paper.

According to the second slide show, the three-sided workstation contains similar items as in the two sided work station. Visible objects that can be acknowledged as fuel include the cubicle walls of the workstation encapsulating the interior in a "U" shape formation, this appear to be made of medium to high-density material most likely plastic and wood. The cubicle has a single shelf running on one side of the workstation and on it are files that appear to have papers in them. Running parallel below the shelf is a desk. The desk appears to be made of the same material as the walls. On the desk, there is a cathode computer screen. Alongside the screen is a collection of files and books others lying on top of the desk and other placed upright next to the screen. There is a computer keyboard at the base of the computer screen. Back of the desk is a seat made of plastic, cloth, foam and metal. Under the desk, two paper boxes, about two feet high that appear to contain reams of paper.

According to the third slide show, the contents of the workstation are not clearly visible. However, it seems as if the four-sided workstation contains the same items as in two sided and three sided workstations above. Having mentioned that, a variety of what is known as organic fuels are present in the workstation. Objects that can be acknowledged as fuel include the cubicle walls of the workstation encapsulating the interior of the "cube" shape formation, this appear to be made of medium to high-density material most likely plastic and wood. The cubicle has a single shelf running on one side of the workstation and on it are files that appear to have papers in them. Running parallel below the shelf is a desk. The desk appears to be made of the same material as the walls. On the desk, there is a cathode computer screen. Alongside the screen is a collection of files and books others lying on top of the desk and other placed upright next to the screen. There is a computer keyboard almost attached to the screen. Back of the desk is a seat made of plastic, cloth, foam and metal. Under the desk, there are two piles of about two feet each of paper.

Amounts of fuel in each

The amounts of fuel in the three workstations are similar. Having looked at the arrangements of each of the workstations, the amount of fuel in them evidently are the same. However, the only differences that exist among the three workstations are the walls or partitioning. The two-sided workstation is half-open and has the two walls or partitioning in a "L" shape. The three sided work station has a "U" shaped wall around it and the four sided workstation is fully covered on all sides leaving a small opening as a door.

Fire Development In Terms Of Heat Flux and Heat Transfer

"The rate of the heat release (HRR) increases or decreases as a Time function is usually expressed in kW per second (kW/s)" (Kennedy & Kennedy, 2003). The slide show reveal that the fire in the four sided workstation developed faster than both the two sided and three side workstation. It took 360 seconds t for the fire to produce 6.9 megawatts of energy as compared to 3.8 megawatts in 480 seconds in three sided workstation. The two sided workstation recorded 3.0 megawatts in 420 seconds.
