Determination of the water requirement depends on the type of users and contemporaneity factor the calculation may be subject to regulations standards or customs that may vary from country to country the calculation method shown below is an example based on practical experience designed to provide a reference value and not a substi tute for detailed analytical calculation 35
Maximum consumption for each delivery point 35
Technical appendix technical appendix technical appendix technical appendix technical appendix 35
The consumption table shows the maximum values for each delivery point depending on the plumbing amenities 35
The sum of the water consumption values of each delivery point determines the maximum theoretical re quirement which must be reduced according to the contemporaneity coefficient because in actual fact the delivery points are never used all together 35
The table of water requirements in civil users shows the maximum contemporaneity flow rate values based on the number of apartments and the type of wc for apartments with one bathroom and two bath rooms as regards apartments with one bathroom 7 drawing points have been taken into consideration while 11 points have been considered for apartments with two bathrooms if the number of drawing points or apartments is different use the formulas to calculate the requirement 35

The flow resistance is calculated using the equivalent pipeline length method according to the table below 41
The table is valid for the hazen williams coefficient c 100 cast iron pipework for steel pipework multiply the values by 1 1 for stainless steel copper and coated cast iron pipework multiply the values by 1 5 when the equivalent pipeline length has been determined the flow resistance is obtained from the table of flow resistance the values given are guideline values which are bound to vary slightly according to the model especially for gate valves and non return valves for which it is a good idea to check the values supplied by the manufacturers 41
