Hi,
Consider the document attached to support your work.
Use the Darcy Weisbach equation with the appropriate f factor for coil as described in the documents underneath.
Iterative calculation on Re number for example.
Note: agree with George about scale formation, very common at my place.
Good...
Hi,
Consult suppliers of filter to define the appropriate filtration system and cartridge.
TDS is one thing, what about the particles size of the solid?
Are you sure about the requirement, this is cooling water? specification is low. Risk to generate high and quick delta P!
Agree with comments...
Pavan,
your mass balance is the following:
Make up water 98.4 t/h
vent : 1.14 t/h
steam to deaerator : 16.47 t/h
feed water to boiler : 113.73 t/h
steam to process : 97.26 t/h
to be tuned.

Just Google Ksb ajax mega m80_250 booklet you will find manual and curves for the entire series. Document under Scrib
BTW why don't you contact Ksb?
my 2 cents

HI,
Download MEASUR you will find example of deaerator.
Are you sure about the operating conditions of the deaerator (Pressure and temperature)? what is the quality of the steam at the discharge of the PRV (steam), pressure and temperature?
Your schematic is wrong, steam is supposed to bubble...
Hi,
The best way to get an answer is to contact the manufacturer/ vendor.
You may also save money and time to ask them to fix the problem if you are not comfortable with the inhouse repair.
Good luck.

Hi,
If I was in your shoes, I will ask my company to give me access to a database and/or ask them to purchase Yaws' Handbook of Thermodynamic and Physical Properties of Chemical Compounds - Yaws 2003. with thousands of components (Organic and Inorganic).
My view only.

Hi,
To avoid this type of question, use always absolute pressure to describe your system.
At the intersection of ducts, the pressure is the same. You need to balance the flowrates in the different ducts to get your answer.
Excel is a good tool for such application , using solver.
Good luck

Hi,
Agree with bimr , regular and periodic backwash will prevent accumulation of contaminants and also prevent the risk of channeling within the bed.
Preventive is better than curative for this type of application.
Make sure you have a way to dispose the contaminant and the AC. In some countries...

Hi moon161,
Affinity law is about Head, not Pressure.
Hi Mohamed,
If your pump is equipped with a wheel (max diameter), the cheapest way will be to trim it.
Check the pump curves Head vs Flow for different wheel diameter
