Hi Gerhardl,
Thank you for your reply. I completely agree with you.
But how I can evaluate the air velocity which is function of the pressure pushing the air and length of the air filled pipe.
Is there any rule of thumb to evaluate the air velocity ?

Hi,
I want to design vaccum breakers/Air releave valves at high elevation points of the offshore platform fire water system. I would like to know is there any guide lines to design these breakers to avoid column seperation. I am looking for the following details.
1.how many number of breakers...
Hi, Thank you for your reply.
The monitor itslef is orifice and act as ARV. DO you think desgining of ARV at monitor will suppress the water hammer pressure?
Hi All,
Fire water system of the offshore platform designed with monitors. The monitors are located away from the deluge skid, the piping between the akid and monitor is air filled. It is observed water hammer pressure during air evacuation from the system. what kind of pressure mitigation...
Hi All,
I am doing the dynamic simulations for the fire water system of the very big offshore plotform. I have evalauted that there is chance of high pressure surges due to column separation at sevaral high points. My question is, how can I evaluate the number vacuum breakers required and...
