A house has 140m^2 of wall area with a thickness of 30cm, and glass area of 8m^2 with a thickness of 0.5cm. Given thermal conductivity of wall =0.69 W/mK and thermal conductivity of glass = 0.78 W/mK. If these are the only mechanisms for heat loss from the house, estimate the rate of heat loss when the inside temperature is 20 degrees C and the outside temperature is -10 degrees C.

PART B: If the house is heated with an oil burner with 80% efficiency how many gallons of oil will be required each day to heat the house?(Assuming 140,000 BTU/gallon)

A plane wall has thickness of 5 cm, thermal conductivity of 2 W/mK and generates heat. The left face of the wall (x=0) has a surface temp. of 80C and has air at 20C flowing past it with a heat transfer coefficient of 50 W/m^2K. If the right face is insulated then the temperature distribution through the wall has a general format T(x)=A+B*x+C*x^2 (a) Draw a properly labeled diagram (including a representative temperature distribution), state all assumptions and calculate the...

Consider a single pane glass window that has an area of 8ft^2 and is 3/16” thick. The outside temperature is -10oC and the inside temperature is 21oC. [9] a.How much heat flows through the window in 8 hours? Use an R-value. b. In reality, all surfaces have a thin layer of air covering them that does not move. This air“film” is about .0005m thick. Calculate how much heat flows through the window in the 8 hour period with the addition...

A factory produces plate glass with a mean thickness of 4mm and a standard deviation of 1.1mm. A simple random sample of 100 sheets of glass is to be measured, and the mean thickness of the 100 sheets is to be computed. What is the probability that the average thickness of the 100 sheets is less than 3.91 mm?

A process that manufactures glass sheets is supposed to be calibrated so that the mean thickness  of the sheets is more than 4 mm. The standard deviation of the sheet thicknesses is known to be well approximated by σ = 0.20 mm. Thicknesses of each sheet in a sample of sheets will be measured, and a test of the hypothesis H_0:μ≤4 versus H_1:μ>4 will be performed. Assume that, in fact, the true mean thickness is 4.04 mm. a) If...
