New calculator – fuel combustion heat energy calculator

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...

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 ...

Re: Biogas Flow in PE80 Pipe

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

Re: Gravity feed to bottom of a lake (very much a newbie)

Power of pump can be calculated as P = Q * (p1 - p2). Pressure drop is due to friction, local resistances and change in elevation between start and end of pipe. So, if you calculate pressure drop in pipe (p1 - p2) for some flow rate, you can also calculate power of pump for that flow rate. And that ...

Re: Orifice plate with pipe taps

What do you mean by pipe taps?
You have corner taps as selection also - if plate is between flanges and taps are on flanges itself.

Re: Gravity feed to bottom of a lake (very much a newbie)

Flow rate through pipe is established based on the energy (mainly pressure) difference from start to the end of pipe. If you have bigger pressure difference flow rate will be higher. If you have same pressure difference flow will be higher when resistances are lower. When you have the end of pipe un...
