each individual cooler
Refer Attachment 8.4 for details of Pipe Sizing, Thickness Calculation
An appropriate PDT will be selected based on the system conditions. The PDTs sizes, pipe thicknesses and pressure rating will be verified with pipe
sizing and thickness calculation.
Determine NPSHA.
The specified NPSHA should be at least 10% less than the calculated NPSHA & shall be round down to nearest 1 mWC to arrive at the design NPSHA.
Refer Attachment 8.6 for details of Pressure Drop Summary Sheet
The design flow of theCCW system is used to size the pump. Thepump shutoffheadis the calculatedTDH plus a 25% margin.The minimum pump
flow is 30% of the calculated design capacity.
The design flow through thepump is theflowforeach of the individual coolers is themaximum operating flow plus a 10% margin, rounding up to the
next 5 cum/hr increment. The design flow of the headers is the sum of the individual cooler design flows in which it serves.
The pipe materials must be acceptable for use at the design temperature and pressure.
PDT selection
Determine CCW piping material.
ASTM A 106 GR. B (S) material is used for CCW Piping
The design flow across PHE,is the sum of flow through individual coolers plus a 10% margin, rounding up to the next 5 cum/hr increment.
Minimum Wall Thickness is calculated as per ASME B 31.1.
Refer Attachment 8.5 for details of Pressure Drop Calc ulation
The maximum operating pressure is based on the minimum flow TDH plus the static head from the high-high water level in the Closed Cooling Water
Head Tank to the lowest point in the system, rounded up to the nearest 0.5 bar. The de sign pressure will be based on the pump shutoff head plus the
static head from the high-high water level in the Closed Cooling Water Head Tank to the lowest point in the system plus 5% margin on the shutoff head,
rounded up to the nearest 0.5 bar.Based on the design pressure and design temperature, a pressure class for the system will selected using ASME
B16.34.The hydrostatic test pressure is calculated as 1.5 times the design pressure per ASME B31.1.
For pump head calculation the cooler circuit with the maximum pressure drop among the various coolers circuit is selected.
Piping frictional pressure drop is estimated based on the design flow.A 10% margin is added to the piping frictional losses.Darcy Weisbach equation is
used for the frictional pressure drop calculation in pipes Crane technical paper 410 is used for calculating pressure drop across valves and fittings.
Pipe size and routing must meet the terminal point pressure at the required flow
Pipe size(s) must keep the fluid flow velocity less than 3.0 m/sec.
Pipe sizes are calculated using the design flows. The minimum pipe sizes are based on maximum recommended velocity limits.
A nominal internal diameter equal to or greater than the minimum diameter calculated is chosen.
PDT selected based on design temp, design pressure and construction material
