Hello,
I would like to calculate the air flow to dilute an explosive gaz volume. Here is my exemple :
LIE 3,3%
Volume of ethanol (Gaz volume)= 50 m3
Building volume : 2000 m3
The volume of ethanol is released in one hour. It's saturated of ethanol vapor.
Could you please help me to calcule...
Hello,
I'm looking for data on nitric acid (60%HNO3) viscosity at 20°C. I found too much different values on internet. Does anyone know a reliable source for this data, or could give me a link to this source.
Isn't there any curve like viscosity vs concentration or viscosity vs temperature...
Hello, I'm looking for data on :
- the specific mass of ethanol in vapor phase at boiling temeperature.
- emissivity of ethanol,
- combustion rate of ethanol.
Could you please help me?
Thanks.
Hello, first of all, many thanks for your help.
My problem deals with an ammonia tank filled up to 85 % with ammonia at 3°C. The tank temperature then reaches the ambiant temperature of 20°C. How can I calculate the final pressure in the tank resulting from this temperature increase?
Hello, my question is relative to a refrigerated ammonia tank (5000 m³) placed in an concrete anular chamber with a roof in which I have to place vent holes. How can I estimate the vent size in order to evacuate the ammonia vapors in case of tank rupture.
The ammonia is stored at -33°C in the...
