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:
What do BAL and BAC stand for? BAL and BAC stand for Blood Alcohol Level and Blood Alcohol Content, respectively. Both BAL and BAC mean the same thing. BAL is the ratio of the alcohol to blood in the body, and is usually calculated as a percentage. The legal limit for driving while intoxicated in most states is 0.08% (0.10% in some states, and 0.02% for minors). BAL/BAC is not the number of drinks a person consumes.
