Dear Azam,   I missed your email in the first place. Strictly as per Clause 5.2 of SA 333-2010 specification addition of these alloying elements are not permitted. However some of the alloying elements may come from the scrap used for steel melting.   What's the quantity involved? and what're the design requirements ?   A re-check of  chemistry by OES spectroscopy would be advisable. If the results of OES conforms to the  results of manufacture's "MTR",  then material is  to be discarded .   If the OES results do not pick up any of the alloying elements as  indicated below , then it would be  projects' discretion (i.e Client. EPC contractor and fabricator joint acceptance).   However talk to the mill in parallel and see if replacement is available , without jeopardizing manufacturing schedule.   Pradip Goswami ,P.Eng.IWE Welding & Metallurgical Specialist ...

Dear Jawedji, From the subject of  fluid mechanics at lower level water pressure is very high due to water head created  between upper level and lower level.it can be calculated as per given below: Head loss=R*g*H Where R=Density of fluid.           g=gravity.           H=head created between lower level and upper level.
