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....

I think that with orifice calculator you can calculate it easily.

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...

Fuel combustion heat energy calculator is developed for calculaton of heat energy (heat power) that is released during combustion of specied fuel for known fuel flow rate. Calculator is also suitable for inverse calculation of fuel flow rate for known heat power. Try calculator at: http://www.pipefl...

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...

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 ...

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 ...

You can use pressure drop calculator and choose to calculate flow rate.

You can try with thermal energy calculator . Here are results that I have with your inputs: Heater/Chiler calculator 1. mass flow rate (w): w : 1.1944578 kg/s 2. volumetric flow rate (q): q : 4.3000445 m3/h 3. density (ρ): ρ : 1000.0 kg/m3 4. diameter (D): D : 60 mm 5. velocity (V): V : 0.422453 m/s...

If K is changing also expansion Y is changing. If you have higher local resistance and K is higher, fluid will expand more.
