Hiya,
I have just gone through my first calculations for expansion joints (EJMA) and used the graphs there to look up relevant Cp, Cf and Cd values.
Anyone got a faster/more accurate way then reading it off those graphs?
Thanks
We use oxygen injection in our metal melting process. The oxygen flow rate is set by adjusting the air pressure (using a pressure regulator)on a pneumatically controlled diaphragm valve which moves a sliding gate in the oxygen supply line.
If you set the pressure in the air to say 40kPa you get...
I was wondering if anyone knew of any water reducing agents or fluidising agents to use in a cement mortar mix that lines pipes which convey potable water.
The additive must be safe to use with potable water. We are hoping to reduce segregation, increase fluidity (easier on our pumps etc.)
