Calculate the size of a main feeder from substation switchgear that is supplying five feeders with connected loads of , , , and kilovolt-amperes (kVA) with demand factors of 95, 90, 85, 80 and 75 percent respectively. Use a diversity factor of the Solution 1- Calculate demand for each feeder: kVA × 95% = kVA.   Information on the calculation of utilization factor tables is available from the Commission Internationale de L’Eclaraige [1, 2]. Calculating the Number of Luminaires Required in a Room Equation 7 may also be rearranged to allow the calculation of the required number of luminaires to achieve a given illumination level.

AA – The alpha-acids of the hops in your recipe, expressed as AA%. U – Hops utilization rates (see chart at the bottom).

P.F: Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. A high power factor signals efficient utilization of electrical power, while a low power factor indicates poor utilization of electrical power. Power Factor is the cosine of the phase angle between current and voltage. These two factors affect the capacity utilization factor as well. According to the reports from MNRE in , the average capacity utilization factor of solar PV plants in India is in the range of %.In particular, solar plants in Rajasthan and Telangana have recorded the highest capacity utilization factor; it being in the range of 20%.The.

While utilization rate is generally applied to people, not objects, you get the idea. In this article, we'll cover the definition of resource utilization, the utilization rate formula, what we can learn from utilization rates, what an ideal utilization rate is and how you calculate it, and how to raise utilization.

1) utilization factor: Utilization Factor or Co-efficient of utilization. It may be defined as “the ratio of total lumens received on the working plane to the total lumens emitted by the light.

Capacity utilization is the percentage of capacity that is actually used. It is calculated using actual output and capacity: capacity utilization = (actual output / capacity) × Depending on the analysis, the calculation of capacity utilization can be based on either effective capacity or design capacity.

maintenance factor (RSMF) is the proportion of the illuminance provided by a lighting installation calculation of utilization factors book a room after a set tim ecop a r dw h u h e nt r omw as cl. Utilization factor(UF) is calculation of utilization factors book proportion of the luminous flux emitted by the lamps which reaches the working plane.

Factors. Note: The luminaires should be placed equidistance to each other for uniform distribution of light in the room. The actual number of luminaires used in the classroom will be less than what we have calculated since the utilization factor of LED lights is better than what we have taken in the calculation although steps will be the same.

The method of calculating the utilization factor (UF) is detailed in lighting design books, although lighting manufacturers’ catalogues give factors for standard conditions.

The UF is expressed as a number which is always less than unity; a typical value might be for a modern ofﬁce building. Floor Multiplying Factor MF 5 Coefficient of Utilization * CU *Coefficient of Utilization from manufacturers literature or Page IES Handbook Number of Fixtures = 50 FC x Room Length x Room Width C.U.

x 4 Lamps x Lumens x M.F. x LLD x x LDD x RSDD = Fixtures Use 8 Fixtures. Calculating Utilization % = Actual Number of Hours Worked (by the resource) divided by the Total Available Hours.

Selecting for any range of time (i.e. weekly, monthly, quarterly, and yearly) provides insight into what projects the resources are spending time on. From this information, project managers and executives can understand what.

Utilization factors are, in practice, only calculated for general lighting systems with regular arrays of luminaires and for three main room surfaces. The highest of these surfaces, the C surface (for ceiling cavity), is an imaginary horizontal plane at the level of the luminaires having a reflectance equal to that of the ceiling cavity.

Measuring resource utilization is a core ingredient to any solid resource management flow. Use the formula to calcualte scheduled and actual utilization. Factors that influence your credit utilization rate Your credit utilization is influenced by three main factors: the opening or closing of accounts, the balance and the credit limit on your accounts.

(1) Demand factor (in IEC, ation factor (Ku)): The word “demand” itself says the meaning of Demand Factor. The ratio of the maximum coincident demand of a system, or part of a system, to the total connected load of the system. Demand Factor = Maximum demand / Total connected load For example, an over sized.

Utilization Factor (body of the table) This is a value between 0 and 1 that represents the percentage of total lamp lumens in the room that fall on the work plane.

It takes into account the room reflectances, room shape, polar distribution and light output ratio of the fitting. Step 2: Calculate. Let us now calculate the value of transformer utilization factor for half wave; center tapped full wave and bridge rectifier one by one. Transformer Utilization Factor (TUF) of Half Wave Rectifier Half Wave Rectifier is the simplest rectifier circuit configuration employing only one diode to convert the AC input into DC.

Hi, Efficiency is = (actual output/Effective capacity), effective capacity would be your benchmark or target set for that task.

Utilization is = (actual output/designed capacity), designed capacity is the target which can be achieved under ideal condition for e.g you have 8 hr/day to work, 8 hrs would be your designed capacity but in real time you are working 7 hrs (excluding break, and ideal.

utilization of available resources. Factors contributing to production line efficiency are manpower utilization and machine efficiency. Measuring the machine efficiency and man power utilization should be on-line, accurate and truthful.

The management should be able to look for relevant production data and to accurately. Overall labor effectiveness (OLE) is a key performance indicator (KPI) that measures the utilization, performance, and quality of the workforce and its impact on productivity. Similar to overall equipment effectiveness (OEE), OLE measures availability, performance, and quality.

Availability – the percentage of time employees spend making effective contributions. To calculate a utilization rate, follow these steps: Calculate the number of hours an employee is on the clock during a standard week.

Calculate how many hours the employee actually works on client work. This can easily be tracked with time log software or calendars. The design is unacceptable if the degree of utilization is > %. Traditional factor of safety against piping. The soil's critical hydraulic gradient is i crit =-= 1.

Factor of safety on hydraulic gradient is F =-= w ik ©0 The degree of utilization using expression (a) is close to %, whereas using (b) it is less than 50%.

What is TEEP. TEEP (Total Effective Equipment Performance) is a performance metric that provides insights as to the true capacity of your manufacturing operation. It takes account both Equipment Losses (as measured by OEE) and Schedule Losses (as measured by Utilization).

TEEP is calculated by multiplying four factors: Availability, Performance, Quality, and Utilization. Assume that the depreciation factor iscoefficient of utilization is and efficiency of the lamp is 40 lumens/watt.

Solution: Area to be illuminated, A = x 10 = 1, m 2. Illumination required, E = 80 lumens/m 2. Total lumens required = A x E = 1, x 80 = 80, Utilization factor = Depreciation factor .For example, to calculate the utilization for a boil gravity of at 30 minutes, look at the utilization values for and These are and, respectively.

There is a difference of 15 between the two, and 7/10ths of the difference is ab so the adjusted utilization for would be - .The utilization factor for tools can be difficult to estimate, therefore calculation values should be compared with measured consumption in similar applications. For example, large air-powered consumers such as grinders and sandblasting machines are used frequently for long periods (3–10 minutes) at continuous operation, despite their low.
