Table 44 230V, 5HP 15.2A convert to 208V (x1.1) 16.72A VA208x16.72x1.736023 Main service - derate 75 and make it continuous 125 6023x.75x1.255646W Considering there is no power factor, I would presume VAW If anything you would error on the high side if there asking for kW.

How do you calculate service demand load by Dalton Hall.Domestic Hot Water Service Systems - Design Procedures - Design procedures for domestic hot water service systems.Water Systems - Hot and cold water service systems - design properties, capacities, sizing and more.Table 220. Now that we have this information added together, we can do the demand factor calculation that is in Table 220.42. = 2.3 (l/s) Total Theoretical Water Flow and Expected FlowĮxpected demand for a supply system at different total theoretical demand can based on the formula above be expressed as So we would add up the three loads (lighting, laundry, and small appliance) and get 4,500 VA + 1,500 VA + 3,000 VA 9,000 VA. Q et = (0.4 l/s) + 0.015 ((50 l/s) - (0.4 l/s)) + 0.17 ((50 l/s) - (0.4 l/s)) 1/2 Transcribed image text: Calculate the main service demand load and select a service ampacity for the farmstead in Exercise 3. If the theoretical demand from all fixtures in a nursing home adds up to 50 l/s and the larges fixture requires 0.4 l/s, the expected water supply demand can be estimated like Example - Main Water Supply to a Nursing Home Using the formula blindly would result in insufficient supply lines. This equation is valid for ordinary systems with consumption patterns likeīe aware when using the equation for systems serving large groups of people where the use is intermittent, like inįor these kind of applications, like a wardrobe, it is likely that all showers are used at the same time.
Note that minimum expected total water flow can never be less than the demand from the largest fixture. Σq n = total theoretical water flow - all fixtures summarized (l/s)
A realistic demand for a supply system will always be far less than the total theoretical demand.Įxpected demand in a water supply system can be estimated as Due to the nature of intermittent use this will unfortunate add up to unrealistic demands for the main supply service lines. The total theoretical demand for a water supply system can easily be calculated by adding known maximum demand for all fixtures in the system.
