Diborane is used in silicon chip manufacture. One facility uses a 500-lb bottle. If the entire bottle is released continuously during a 20-min period. It is a clear, sunny day with a 5mph wind. Assume that the release is at ground level

a. Determine the location of the 5 mg/m3 ground-level isopleth.

b. Assume now that the bottle ruptures and that the entire contents of diborane are released instantaneously. Determine, at 10 min after the release,

(1) The location of the vapor cloud. (2) The location of the 5 mg/m3 isopleth. (3) The concentration at the center of the cloud.

(4) The total dosage received by an individual standing on the downwind axis at the 15-min downwind location.

(5) How far and long the cloud will need to travel to reduce the maximum concentration to 5 mg/m3

Work is highly appreciated, thanks!

Wire electrical-discharge machining (WEDM) is a process used to manufacture conductive hard metal components. It uses a continuously moving wire that serves as an electrode. Coating on the wire electrode allows for cooling of the wire electrode core and provides an improved cutting performance. An article gave the following sample observations on total coating layer thickness (in µm) of eight wire electrodes used for WEDM. 22 17 29 35 43 25 25 25 Calculate a 99% CI for the standard...
