For In-class Problem #1, we calculated the minimum temperature of air that could be blown over a sheet of glass that could cool it without causing it to crack. In this problem, it was assumed that the glass has a thermal conductivity k = 1.4 W/m-Kand the heat transfer coffecient for the air blown over the surface was $h_c$=5.2 W/m²-K. In this problem, the goal is to determine whether this was a realistic estimate for h and to use the predicted value of to determine the cooling rate of the glass under the following conditions: Support rolls Forming ro Molten glass $T_\infty$=27 C $T_s$ = 107 C 0.5 m/s conveyer 이 The glass sheet is 1.5 m wide, 1.5 mm thick, and has been sliced off just past the forming rolls to create a sheet that is 2 m long. In this estimate, assume that the support rolls do not interfere with the air movement over the glass as it moves along the conveyr belt at 0.5 m/s. At a point where the glass has cooled down to 107°C, the bulk air is stagnant and at 27°C. 2.0 m $T_\infty$=27 C a) What is the average heat transfer coefficent for the glass sheet at this point on the conveyor belt? Evaluate the properties at the film temperature. b) What is the rate of heat loss in watts from the sheet at this point on the conveyer belt? c) If the sheet was poly(methyl methacrylate) (Plexiglas) with a thermal conducticity of 0.12 W/m-K, but otherwise has the same dimensions, temperature as the glass sheet, and the air is at the same conditions, what is the rate of heat loss from the Plexiglas sheet?

This fungus likes hot, moist, dark areas like public showers and athletic mats. The highly infective form can be described as round, raised, and pink to red, and it usually does not get more significant than a quarter. When grown in the lab, it is powdery to granular and cottony and can be anywhere from white, yellow, or pink and white, white, yellow, or red-brown on the back. Microscopically, the macroconidia can be pencil-shaped, and the microconidia can be teardrop-shaped. According to above provided information, What can you add to the likely identity or information about this organism that tells you it is a fungus? Do you know what the unknown FUNGUS AMONG US most likely is? You can be generic in this description, or you can provide a scientific genus or species if you feel you have sufficient information to hypothesize on the identify of the unknown FUNGUS? In looking at the environment, what type of illness or disease may this FUNGUS AMONG US cause in a patient? What type of transmission would be potentially associated with this FUNGUS?

A group of elementary school students went on a field trip to a local farm. While there they petted goats and sheep. They also helped the farm staff collect eggs from the chicken coop. Bagged lunches were provided by the school and consisted of a peanut butter sandwich, and apple, a bag of corn chips, and bottled water. Three to six days after the trip ~40% of the students in the classroom came down with diarrhea. Since this was a small town, 9 of those students ended up going to the same pediatrician for treatment. The physician made the following observations from stool samples collected from his patients: Seven of the nine students had a unique bacterium present in the stool compared to healthy controls.
