	Demand Factor (Site not responding. Last check: 2007-10-08)
		The demand factor is defined as the ratio of the maximum demand of a system (or part of a system) to the total connected load for that part being considered.
		The demand factor is always equal to or less than one.
		The "connected load" would be reduced by the appropriate demand factor and diversity factor when sizing the service entrance conductors.

	Power and Voltage Requirements
		Knowledge of the maximum demand of groups of loads is of great importance because it is the group maximum demand that determines the sizes of conductors and apparatus throughout the electrical system.
		Since the maximum demand is one of the factors determining the size of conductors, it is important that the demand factor be established as closely as possible.
		Knowing the demand factors for various types of buildings and installations is also beneficial when existing facilities are rearranged because increased serving capacity is often not required, even though the connected load is greatly increased.

	Demand load (Site not responding. Last check: 2007-10-08)
		Note: The demand load is the sum of the operational load[?] (including any tactical load[?]) and nonoperational demand loads.
		It is determined by applying the proper demand factor to each of the connected loads and a diversity factor[?] to the sum total.
		At a receiver facility, the power required for all receivers and auxiliary equipment that may be operated on prime or spare[?] antennas simultaneously, those in standby condition, multicouplers, control and keying equipment, plus lighting, ventilation, and air conditioning equipment required for full continuity of communications.

	Should I have regularly scheduled or on-demand clotting factor replacement therapy for hemophilia?
		Clotting factor concentrates are not always effective because the body can develop antibodies called inhibitors, which destroy the newly introduced factor VIII or IX.
		Clotting factor replacement therapy is a way to introduce missing or inadequate amounts of clotting factor VIII or IX components into your blood.
		Recombinant clotting factors are produced in a lab (using recombinant DNA technology) and are not derived from donated blood.

	Thunderbyrd Power Systems - Reliable Power Factor Correction and Power Conditioning Systems
		A power factor of 1.00 of unity, means that all of the power consumed by a facility goes to produce useful work.
		The effective power factor may be lower in the presence of non-linear devices (such as solid-state or switched power supplies, variable speed drives, DC drives) and the harmonic distortion that these devices generate.
		More and more utilities are introducing power factor penalties (or kVA-based demand charges) into their rate structures, in part, to comply with provisions of the Clean Air Act and deregulation and to some extent in response to growing competition in a newly-deregulated power market.

	Understanding Electricity (Site not responding. Last check: 2007-10-08)
		Demand is the rate at which electric energy is delivered to or by a system at a given instant or averaged over any designated period of time.
		Coincident Demand is the customer’s KW usage during a 15-minute interval within the time period when peak usage for the utility occurs.
		Non-Coincidental demand is the customer’s maximum KW usage during the billing period with a certain time interval of 15 minutes.

	Safety Stock Calculation
		Factor used as a multiplier with the Standard Deviation to calculate a specific quantity to meet the specified service level.
		The standard deviation was based on the forecast period, a factor is necessary to increase or decrease the safety stock to allow for this variance.
		The safety stock calculated for demand variation will also cover for some supply variations, however, the best way to deal with variable supply is to have a high level of communication with the vendor and not to count on safety stock.

	Capacitor ratings and installation
		Demand is measured over 15 or 30 minutes, so a small change for a few seconds will not change the demand.
		I do not know what is meant by demand factor, but once you dimension the capacitors correctly, you should reduce your bill since the current incoming from the power source to the connection point of the capacitors will be reduced.
		Their benefit is in reducing the power factor, but most utilities do not have a power factor charge (or it is very small).

		On the horizontal axis N is the number of units of the factor, on the vertical axis, Q is the Total Output.

		factors of production than before, which they will want to purchase from their suppliers, shifting the demand curves for each of the factors to the right.
		(This increase in demand for the factors in turn will tend to raise the factor prices somewhat and to increase the quantity of them sold, which then affects the factor producers' demand for their own necessary inputs and brings about further price-and-quantity adjustments throughout the economy in an ever-widening ripple effect.)

	The Profit Function

		The additional demand factors in the Summary of Estimated ORC Requirements table on the ORC spreadsheet are safety factors that account for uncertainty about potential sinks for oxygen.
		These factors are used to increase the ORC dose by the specified multiplier and provide contingency to account for the many uncertainties inherent in subsurface investigations and in-situ remediation projects.
		The inclusion of a safety factor/additional demand factor is a typical engineering design technique used to provide a conservative estimate for the amount of HRC necessary for subsurface systems that have a high degree of variability and are minimally sampled for chemical/hydrological parameters.

		However, the NEC does not cover the diversity factors to be used in sizing motor(HVAC, etc) loads for the type of facilities.
		We have a debate going in our office as to what diversity factor might be used for the entire building load vs applying diversity factors to each element of the load(lighting, receptacle, motor, resistance heating, etc).
		What you are calling diversity factor in the NEC is called demand factor and is defined as the ratio of the maximum demand of a system, or part of a system, to the total connected load of a system or the part of the system under consideration.

		The chart clearly says for the type of structure what the demand is per square foot.
		My question is if you have a restaurant, which will be a continuous load, does the NEC already take that into accout when you use the 2VAs per square foot, and you go to the demand factor chart and it tells you it is at 100% or do you have to then multiply by 125%.
		The NEC does not say you have to multiply general lighting by 125% if its going to be a continous load like a restaurant would be however we are being told we should.

		Because the demand curve reflects the VMPL, in equilibrium workers receive the value of their marginal contribution to the production of goods and services.
		An important lesson: any event that changes the supply or demand for labour must change the equilibrium wage and the VMPL by the same amount, because these must always be equal.¡R$Z~Z$Ìªt??7= fó ª ¨Shift in labour supply.
		When labour demand increases from D1 to D2, the equilibrium wages rises from W1 to W2 and employment rises from L1 to L2.

	Clearing Up Multi-Family Dwelling Unit Calculations
		You can use a demand factor of 75% for four or more appliances fastened in place, such as dishwashers, waste disposals, trash compactors, or water heaters, but not space-heating equipment (220.15), clothes dryers (220.18), cooking appliances (220.19), or air-conditioning equipment.
		It shows that the demand factor must be calculated based on the formula: %=35-[0.5×(number of dryers-23)].
		Another factor that you need to consider is the house panel for the loads not found in the individual apartments, such as corridor lighting, outside lighting, parking lot lighting, sign lighting, or maybe even a sprinkler system.

		So, the demand for inputs is derived from the demand for outputs.
		This idea of derived demand may seem like just a matter of language but it turns out to be crucial in understanding how the demand for inputs arises and how factor demand changes when demand for outputs changes.
