Natural Gas - calculating pressure drop

View the thread, titled "Natural Gas - calculating pressure drop" which is posted in Gas Engineers Forum on UK Plumbers Forums.

I'm pretty sure Worcester suggest upgrading the first 3m of gas pipe from the meter to 28mm
 
I shouldn't but you should. I expect a 'professional' to come to my house and show me a mathematical equation proving that I need to pay to put in wider pipe. I expect that someone who is charging £50-70 an hour can do that. Is that asking too much?

I know your sort. The guys on this forum have been more than helpful. Vern posted a mathematical formula for you. I really do not know what more you want. If you want a plumber to come round with the total calculation formula; I will come round and it will cost you £200 per hour. Or Some one else can come round with a screw driver leak detection fluid and manometer for £50 per hour. I guess the latter is more likely.
