Pressurized steam at 4 4 0 K flows through a long, thin-walled pipe of 0.64 m diameter. The pipe is enclosed in a concrete casing that is of square cross section and 1.45m on a side. The axis of the pipe is centered in the casing, and the outer surfaces of the casing are maintained at 340 K . What is the rate of heat loss per unit length of pipe?
Webster Chemical’s nominal weight for filling tubes of caulk is 8.00 ounces ± 0.60 ounces. The target process capability ratio is 1.33. The current distribution of the filling process is centered on 8.054 ounces with a standard deviation of 0.192 ounces. Compute the process capability ratios Cp and Cpk to assess whether the filling process is capable and set properly.

West Battery Corp. has recently been receiving complaints from retailers that its 9-volt batteries are not lasting as long as other name brands. James West, head of the TQM program at West's Austin plant, believes there is no problem because his batteries have had an average life of 60 hours, about 10% longer than competitors' models. To raise the lifetime above this level would require a new level of technology not available to West. Nevertheless, he is concerned enough to set up hourly assembly line checks. Previously, after ensuring that the process was running properly, West took samples of 5 9-volt batteries for 25 test to establish the standards for control chart limits. Those 25 tests are shown in the following table: Sample Data Sample Data Hour Hour Sample Taken 1 Sample Taken 1 2 4 5 R 2 3 4 R 1 60 61 60 59 67 61.4 8 14 62 69 51 62 56 60.0 18 55 57 70 56 46 56.8 24 15 67 53 63 69 70 64.4 17 60 45 58 49 57 53.8 15 16 72 58 51 44 64 57.8 28 66 81 61 51 60 63.8 30 17 49 49 58 68…

A rigid vessel having a volume of 0.05 m³ initially contains carbon dioxide gas at temperature 25°C and pressure p. Ethylene gas is allowed to flow into the tank until a mixture consisting of 20% carbon dioxide and 80% ethylene (molar basis) exits within the tank at a temperature of 25°C and a pressure of 100 bar. Determine the pressure p, in bar, using Kay's rule together with the generalized compressibility chart. Answer: 46.6 bar
