Thanks CHD01 for your comments. Could you direct me where I can find the API gas dispersion formulas? Also, to put an extra spanner in the works, the temperature drop of the calculation will also involve taking into account the latent heat of condensation, and subsequently the flow of the jet...

I would like to thank everyone for your responses to date. I would still like to hear from anyone who has done some design calculations to estimate the distance the jet of steam needs to travel from the ruptured pipe before its temperature reaches 70C. I've estimated the steam velocity for 10.5...

In light of the recent fatalities at the japenese nuclear plant caused by the rupture of high pressure steam pipe which caused fatal burns, could someone tell me how I could calculate what safe distance a person needs to be away from the pipe in case of rupture. My steam pipes carry 10barg...

Sorry rmw, I have been too brief. Here are the answers to the questions: 1. I refer to bump over to mean carry over of liquor along with the vapour route. 2. The heat source is heating coils and a jacket. It is heated by a continous supply of 2barg saturated pressure steam. The evaporator is...

I am working for a client who has an evaporator operating under vacuum at 70mmHg which suffers from regular bumpovers. The liquor feed is a mixture consisting of nitric acid and water fed at approx 35C and is fed continuously. During operation, the evaporator has no liquid outlet flow and the...
