Potable Water Critical Pressure Calculation

There are two methods for the determination of Potable Water Critical Pressure Calculation.
Kritik Basınç Hesabı

Critical Pressure Calculation TS1258 Method

The plumbing is the sum of the losses occurred in friction and local scope of pipes, Rline arthritis factor taking into account the prepared tables are read. Table 1 in steel and cast iron pipes prepared for values. According to these tables in a variety of diameters and L.t. and conveys the pipes 1 mt long and the total average pressure occurring loss. Fresh water plumbing must be between 1 m/s to 2 m/s speed. Very sensitive to sound in applications such as hospital speed 1 m/s below, your voice is trivial is above 2 m/s in industrial applications (up to 3 m/s) values. Therefore, this table is selected, the speed of the pipe diameter and pipe it is possible to determine the specific total pressure loss.

Critical Pressure Account DIN 1998 Account Method

As with other pipe and channel installation friction loss and individual values and calculate local losses total on multiply a coefficient to take into consideration pollution method:
Total pressure loss, ΔP = ∑ R. L + Z can be found with the expression. Here;

R = coefficient of friction, L = tube Length; Z = Local pressure loss.

This is in line with the TS1258 standard or DIN 1998 you can calculate the system according to the pipe diameter. In our country, more TS1258 according to the standard calculations.

TS1258 Used As A Formula Accounting Method

Article 1 also mentioned pressure loss values can read from the table or steel tubes can achieve in a table with the following formula.
Formula = (7,289 * L.t. ^ 1.01)/((D/10) ^ 5.49)
Y. B = Loading Unit
Diameter = Pipe Nominal diameter (mm)
