The âtransformationâ of straight pipe to bent pipe takes place in the heated narrow annular zone which moves continuously along the length of the bend as the bending process advances (Figure 1). The heating of this zone is effected by means of an induction ring (Figure 2).
Budget at Completion (BAC) is the total budget allocated to the project. BAC is generally plotted over time. For example, periods of reporting (Monthly, Weekly, etc.) BAC is used to compute the Estimate at Completion (EAC), explained in the next section. BAC is also used to compute the TCPI and TSPI. BAC is calculated using the following formula:
Blood alcohol concentration (BAC) is the ratio between alcohol and blood in the body. For example: a 0.08% BAC means that there is eight drops of alcohol to 9,992 drops of fluid based on the volume of 10,000. Therefore, it can be seen that an illegal level may be reached with small amounts of alcohol. For those under age 21 or anyone with an alcohol restriction, any amount of alcohol is illegal.
