Chapter 5, Problem 5.39P
Consider the wall section shown in Fig. -4a, construction 1, and estimate the temperature of the inside surface of the concrete block at the furring. The outdoor temperature is 1 F (—17 C) and the inside temperature is 72 F (22 C) with a relative humidity of 45 percent. Would you recommend a vapor retardant? If so, where would you place it? Explain.

- A 5.00-ml. sample of blood was treated with trichloroacetic acid to precipitate proteins. Alter centrifugation, the resulting solution was brought to a pH of 3 and was cxtraccd with two 5-mL portions of methyl isobutyl ketone containing the organic lead complexing agent APCD. The extract was aspirated directly into an air-acetylene flame yielding an absorbance of 0.454 at 283.3 nm. Five-milliliter aliquots of standard solutions containing 0.240 and 0.475 ppm Pb were treated in the same way and yielded absorbancc of 0.412 and 0.642.

Typical consumption of wood is 1 kg person–1day–1. (a) Estimate the heat energy required to boil a 2-liter pot full of water. Assuming this to be the cooking requirement of each person, compare this with the heat content of the wood, and thus estimate the thermal efficiency of the open fire. (b) How much timber has to be felled each year to cook for a village of 200 people?Assuming systematic replanting, what area of crop must the village therefore set aside for fuel use if it is not to make a net deforestation? Hint: refer to Table 10.4. (c) Comment on the realism of the assumptions made, and revise your estimates accordingly. Answer: (a) mcDT ≈ 0.6 MJ (heat losses from pot imply actual requirement is higher). h ≈ 3%. (b) 70 tonnes; 7 ha.arrow_forward

- Which statements about case hardening are correct? The process makes it possible to harden local areas of the component. The process promotes a fine-grain structure due to relatively low heating temperatures. Case hardening is particularly useful for austenitic steels Case hardening is well suited for small workpieces. During case hardening, the workpiece is specifically enriched with carbon and nitrogen.
