ultragas systems pressure losses z caused by individual points of resistance in the pipes 1 the following individual points of resistance are used as examples for calculation in addition to pressure losses caused by friction pressure losses can also be produced by deflection in the valves in piping network for example by non-return valves angles elbow bends or other branching sections the pressure losses at the individual points of resistance in the pipes depend on the size of the components installed and on the flow velocity and density of the flowing medium the design and size is expressed by the resistance coefficients ξ zeta these are benchmarks that have been determined in tests 2 3 4 5 6 ξ values for calculating the pressure loss at the individual points of resistance 7 9 10 11 12 13 individual point of resistance ξ value straight-way cock 0,2 right angle stopcock 2 elbow bend 90° 0,5 tiered elbow bend 0,5 y-piece 1,5 straight-way t-piece 0,5 t-piece branch 1

ultragas systems 18 water quality – desalination 2 to decide whether the plant filling water has to be desalinated or not we need to know the following data 3 we need to check the conductance of the filling water in our example we have a value of 520 μs/cm • heating power • water volume of the plant • total hardness of filling water • conductance of filling water 4 5 with this data and maximum three further steps we are able to qualify if the plant has to be desalinated or not 6 in our example heating power water volume of the plant filling water total hardness conductance 7 8 18.2 step 1 – conductance of filling water we have to search the intersection inside the installed boiler capacity in our case the boiler capacity is 125 kw which refers to line “50 to 200 kw” the intersection gives us the result “desalination or water analysis now we have the choice to make a desalination without checking the water quality or to check
