(b) The brick wall of a building has dimensions of 4 m by 10 m, and it is 15 cm thick with a coefficient of thermal conductivity of 0.8 W.m1ec1. How much heat flows through the wall in a 12-hour period when the average inside and outside temperatures are 20 °C and 5 °C respectively? Will a 2 kW heater operating in the room compensate for the heat loss? Justify your answer. A layer of insulating material of thickness 5...

Heat Loss and Heating Costs of a House Part A A house has well-insulated walls 17.1 cm thick (assume conductivity of air) and area 411 m2, a roof of wood б.бб cm thick and area 279 m2, and uncovered windows 0.626 cm thick and total area 33.4 m2. Assuming that the heat loss is only by conduction, calculate the rate at which heat must be supplied to this house to maintain its temperature at 21.4°C if the outside temperature is...

Calculate the rate of energy loss due to thermal radiation from an unclothed person if the average skin temperature is 37 °C and the room temperature is 20 °C. You may sume a total surface area of 1.5 m and a skin emissivity value of 0.9. How much energy (from food) must be consumed per day to compensate for this loss? If the person is surrounded by a layer of insulation of thickness 1.0 cm with a thermal conductivity of...

Calculate and answer the following question on gene frequencies. Please show how you calculated the gene frequencies! a. Gene frequency. Much of detecting changes in evolution revolve around tracking gene frequency. You need then to know now to calculate gene frequencies and monitor changes in such. Calculate the following gene frequency. You sample a population of annual flower in 2002 and find the following phenotype frequencies: Red: 100, Pink: 200, White: 100. b. You return to the population in 2003...

For high technological industries, you evaluate metals and ceramics beyond the Fe-c alloys to more costly applications. A. Select three alloying components for Ti alloys to give alpa+beta phases from simple solidification or peritectic reaction and beta+gamma phases from a eutectic reaction. B. What alloying elements should you seek for stainless steel to have a bar or plate with 50% austenite and 50% ferrite, with a significant martensitic phase, with reduction of sensitization and with reduction of pitting corrosion? C....

If you lay one tape (A) sticky side up on a table (without discharging it) and bring the other (B) close above it you should be able to determine the distance at which the repulsive Coulomb force is equal to the force of gravity on tape B. Assume that the charges are equal on the two tapes (they were prepared the same way!), and the mass of scotch tape is roughly 1 gram/meter (it is pretty accurate, I just measured...
