To all,

 

I need your help. I am trying to calculate the Methyl Acetate leaking though 2" pipe from the pressurized storage tank. There is a glass in chamber foam, but the glass was broken, now the Methyl Acetate leaking through this 2" size. I want to calculate how much the vapor is releasing from the pressurized storage tank.

 

Please help me. thanks

Only you can perform the work because  you did not provide much information about the conditions ( P, T ,...)

Help yourself we will help you.

Dear Breizh,

 

The temperature is 70F and the pressure is 3.88 Inches of Water with 22% of MeAC in the mixture.

 

Thanks
