*Example Of Supply And Demand Calculating expected demand of water supply in 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. Due to the nature of intermittent use this will unfortunate add up to unrealistic demands for the main supply service lines. A realistic demand for a supply system will always be far less than the total theoretical demand.
System water demand is the quantity of water that the treatment plant must produce in order to meet all water needs in the community. Water demand includes water delivered to the system to meet the needs of consumers, water supply for fire fighting and system flushing, and water required to properly operate the. Figure 6.1.2-1 – Daily. Engg. physics material for 20192020applied physics. Design of water systems requires estimates of expected water demands applicable to the sizing of system pumping equipment, transmission and distribution lines, and storage facilities. Estimating water demands (i.e., average day, maximum day, and peak hourly demands) may be. PREFACE December 1998 T he field of water resources covers a wide range of topics and s ubject matter. This handbook focuses on one of those, the issue of water supply. Direct cross connection is a piping system connecting a raw water supply, used for industrial fire fighting, to a municipal water system. An indirect cross connection is an arrangement whereby unsafe water, or other liquid, may be blown, siphoned or otherwise diverted into a safe water system.
Expected demand in a water supply system can be estimated as
qet = qnl + 0.015 ( Σqn - qnl ) + 0.17 ( Σqn - qnl )1/2 (1)
where
qet = expected total water flow (l/s)
qnl = demand of largest consumer (l/s)
Σqn = total theoretical water flow - all fixtures summarized (l/s)
Note that minimum expected total water flow can never be less than the demand from the largest fixture. This equation is valid for ordinary systems with consumption patterns like
*homes
*offices
*nursing homes
*etc.2.1 Demanddesign Water Supply Systems
Be aware when using the equation for systems serving large groups of people where the use is intermittent, like in
*hotels
*hospitals
*schools
*theaters
*wardrobes in factories
*etc
For these kind of applications, like a wardrobe, it is likely that all showers are used at the same time. Using the formula blindly would result in insufficient supply lines.Example - Main Water Supply to a Nursing Home
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 likeDemand Supply And Price
qet = (0.4 l/s) + 0.015 ((50 l/s) - (0.4 l/s)) + 0.17 ((50 l/s) - (0.4 l/s))1/22.1 Demanddesign Water Supply System
