Calculating man hours involves determining how much time a project requires and how many employees are needed. The process can be completed before or after a project, and this example determines man hours after a project's completion. The calculations take a few minutes and require a calendar and a calculator.
Know MoreUse a calendar to determine when the project began and ended. Count how many work days the project ran, being careful to subtract holidays when employees were not working. For this example, assume the project ran for eight five-day weeks, for a total of 40 work days.
Determine how many hours your employees work each day, and do not count any unpaid time, such as lunch breaks. Assume that each employee works eight hours a day. Multiply the project's work days by a single employee's daily number of hours. In this example, 40 x 8 = 320. This is the number of hours a single employee spends on the project over the eight-week period.
If more than one employee is assigned to the project, multiply the number of employees by the answer listed in the previous step. If one employee spends 320 hours on the project, and five employees are assigned to the task, 320 x 5 = 1,600. This is the total number of man hours performed on this project.
Calculating the occupant load of a room or building requires first calculating the area of the space in question in square feet, and then dividing the area by the occupant load factor specified by the International Building Code. The resulting number from this calculation determines how many occupants can legally use the space at one time.
Full Answer >According to Newton's Second Law of Motion, force is equal to the product of mass and gravitational acceleration. The formula is F=mg. Because weight is also a force, you can calculate the mass of everyday objects by using the same formula.
Full Answer >Exponential growth and decay can be determined with the following equation: N = (NI)(e^kt). In this equation, "N" refers to the final population, "NI" is the starting population, "t" is the time over which the growth or decay took place and the "k" represents the growth or decay constant. If necessary, this equation may be rearranged to find any of these variables.
Full Answer >A linear foot, otherwise known as a lineal foot, is equivalent to any one-foot length of a long object, and there is no difference in length between one linear foot and one foot. Particular industries, such as construction and archiving, use the term linear foot to avoid confusion with the square foot or cubic foot.
