Utilization Factor = The time that a equipment is in use./ The total time that it could be in use. Example: The motor may only be used for eight hours a day, 50 weeks a year. The hours of operation would then be 2000 hours, and the motor Utilization factor for a base of 8760 hours per year would be 2000/8760 = … See more Utilization Factor (UF) Maintenance Factor (MF) Equation for Required Illumination is. E = N (n x φ) x MF x UF / A. See more The ratio λ/μ is called utilization ρ. If this ratio is greater than 1, that says customers are arriving faster than they can be served, and so the line will grow without … See more The utilization factor of the lights affects how the lighting in your home is perceived, as well as the total effectiveness of the lighting arrangement. What is Utilization … See more WebOct 15, 2014 · To account for this, a measure called the utilization factor (UF) is used. This is a measure of the total amount of light from a luminaire that reaches the task, both directly from the luminaire and indirectly through reflection from room surfaces.
