@ Georgeverghese.
Thank you for your kindness.
I think there is an error somewhere, formulas, units...
You can refer "HEAT AND MASS TRANSFER STUDIES IN LIQUEFIED PETROLEUM GAS STORAGE OPERATIONS, Zainal Zakaria, 2006". A long-term experiment about vaporization.
Truly sincerely thanks again.
@ Crshears;
Yeahhhh.
In fact, if the pressure in the cylinder is less than 0.2 bar, it is considered empty. (You can't use more than). residue remaining at the bottom of the cylinder considered too small to ignore.
It has a negligible effect on forklift's cylinder.
@ Compositepro;
I think you're misunderstanding this topic.
Do you have a formula to calculate how many kg/h a LP gas cylinder (45kg/47kg) of natural vaporization maximum can hold?
With 20 kg/h, u can installed 16 cy;inder (8 use and 8 stand_by), still ensuring legal conditions. If used...
@ Georgeverghese:
My teacher gave me a long time "Evaporation rate between gas - liquid phase". I don't remember... ;))
@ Compositepro, @ all:
Natural vaporization (off-take) of LP gas cylinder is maximum.
it means if Customer uses more than 20 kg/h then vaporizer must be installed (Max 700 kg...
Dear Pierreick;
Is it true with the LP Gas cylinder?
Why not calculate the way Conduction heat transfer?
What different when the cylinder is vertical and the bottle is horizontal offtake?
Dear LittleInch;
I used temperature gauge to measure liquid LP Gas in cylinder. It is 25 0C at tropical country.
I don't understand how to calculate it.

I think law's LP Gas are similar across countries.
Can you...
Dear LittleInch, Georgeverghese;
I also think people using 2rd method. But heat tranfer formulas (conduction vs radiation) is deference.
How to calculate 2,37 kg/h? 5 kg/h?
What my values wrong...

Hello friends,
I am trying to calculate the natural vaporization Q for a LP Gas cylinder (99 liters or 45 kg LPG). If I do the Q=(m*k*As*Psat)/Rg*Tl equation it turns out 11,9 kg/hr.
If I do Q=K*Aw*(Ta-Ts)/Cv is 1.38 kg/h
So what am I missing?
Thanks

m (molecular...
