Re: Reducing pressures with Orifice Plates
Calculator gives option for enter either density or temperature. If you choose to enter density, than calculator using R is calculating T prior to other calculation is done. I can't tell you about pipe roghness you should use. I think that it is the best way to be on safe side and choose values of p...

Re: Reducing pressures with Orifice Plates
Kappa is for expansion factor ISO 5167 - Y for orifices, you have it in the right middle of this page: http://www.pipeflowcalculations.com/pipe-valve-fitting-flow/flow-in-valves-fittings.php R is simply used for calculations between rho, T and p in ideal gas state equation, depending on user inputs....

Re: Reducing pressures with Orifice Plates
Hello, Gas constant for CO2 is R=189 J/kgK and k=kappa=Cp/Cv=1.3 for CO2. These values are needed for calculation. You have table at: http://www.pipeflowcalculations.com/tables/gas.php . I suggest you to use check button with "use ISO constraint" just to be sure if calculation is within it...

Re: Java version problems - plans to upgrade this website?
As older Java is used that means that with new Java version you can run calculators, with no problems. But for security reasons you are requested to update java to version 51 which is 1.7, at least. Update of this site is undergoing and calculators one by one will be redesigned to new technology and...

Re: nat gas pressure drop arguement
or if I used another example where the meter outlet connection was 3/4inch pipe, but the pipework required was worked out to be 1 1/4 inch, wouldn't the 3/4 inch outlet cause a huge pressure drop? and if you were only allow to have a working pressure drop of 1 millibar from meter to appliance, you ...

Re: nat gas pressure drop arguement
hi folks. can someone of higher intelligence than me please settle this argument between my friend and I. I say that. if you had for example a one inch gas pipe for 10 meters, then reduced to half inch for 2 meters and then increased back to one inch for a further 10 meters,, that there would be a ...
