01. O tempo de reverberação (TR) é um indicador de excelência acústica, e cada ambiente deve ser avaliado segundo a sua necessidade. O tempo de reverberação (TR) é o tempo que o som permanece audível depois de cessada a fonte e está relacionado à capacidade de absorção dos materiais das superfícies expostas. Analise as afirmativas a seguir:

I – A indicação do TR ótimo de um ambiente, segundo a NBR 12179 (1992), é obtida através do cruzamento de dados como área e volume dele.

II – Se um ambiente tem um valor de TR alto e preciso baixar, a aplicação de materiais absorventes nas superfícies pode resolver.

III – O TR somente pode ser calculado para ambientes prontos, nunca projetos.

IV – Para fazer o cálculo do TR através da fórmula de Sabine, é essencial conhecer o volume total do ambiente.

V – O conforto acústico nas grandes cidades é extremamente importante, e avaliar o TR de praças e espaços aberto é uma forma de garantir que esses sejam confortáveis e adequados.

Considerando a avaliação do TR de um ambiente, verifique quais asserções são verdadeiras e assinale a alternativa correta:

Ashielded metal arc-welding operation is accomplished in a work cell by a fitter and a welder. the fitter takes 5.5 min to load components into the welding fixture at the beginning of the work cycle, and 1.5 min to unload the completed weldment at the end of the cycle. the total ength of the weld seams 1200 mm, and the travel speed used by the welder averages 300 mm/min. every 600 mm of seam length, the welding stick must be changed, which takes 0.8 min. while the fitter is working, the welder is idle (resting): and while the welder is working the fitter is idle. (a) determine the average arc-on time as a fraction of the work cycle time. (b) how much improvement in arc-on time would result if the welder used flux-cored arc welding (manually operated), given that the spool of weld wire must be changed every 10 weldments, and it takes the welder 5.0 min to accomplish the change? (c) what are the production rates for these two cases (weldments completed per hour)? attach your work and solutions.

1in2 processor chip can be modelled as an isothermal plane wall of silicon, isothermal on both sides. the power input to the bottom of the plane wall, or the processing power of the chip, often called the thermal design power (tdp), is 100w. assume the periphery is adiabatic. the silicon is 400 microns thick. the temperature at the junction, or in this case on the bottom of the isothermal plane wall, is 85°c. what is the top surface temperature, assuming that the only mode of heat transfer is conduction
