The magnets align with the Earth's magnetic field, and the pilot reads the direction on the scale opposite the lubber line. Total Float (TF) = Total Slack = LF – EF = LS – ES = LF – ES – d Another type of float often used in network analysis is the Free Float, which can be calculated as: Free Float = Es (of succeeding activity) – EF (of activity in question) The free float defines the amount of time that an activity can be delayed without taking float away. Solid Waste Engineering. Free Float: The amount of time that a schedule activity can be delayed without delaying the early start date. You can calculate the total float by subtracting the Early Start date of an activity from its Late Start date. 4. 4 is the difference between the earliest start date of an activ ity and its latest start (or the difference between its earliest finish and its latest finish). The necessary dimensions are as below: V=6±0. Q. Check out for more free engineering tutorials and math lessons!Project Management Tutorial: Determine Total Float & Free Float (. Once this has been done, the total float of any activity is simply the difference between the latest finishing time (LF) obtained from the backward pass and the earliest finishing time (EF) obtained.
