Hello
I'm doing a review of some old (30 years plus) acid tanks, containing 96% sulphuric acid. Some are atmospheric tanks, some are designed for 2barg internal pressure. Although I can find no specific references in standards (BS or API) it is my understanding that atmospheric tanks should be...
Hello
I'm looking at a design where I'm pumping from approx ground level (say 0m), over a pipebridge (7m elevation) to a vessel (1m) which is open to the atmosphere. The downhill part of the pipeline is a near vertical drop. My thoughts are to treat the headloss design for the pump duty point...
Hello
Looking at a pumping system comprising 3 VSD centrif pumps discharging into a rising main. Pumps can run either on their own or any 2 in parallel. I want to ensure that in parallel the load is shared and pumps run at same speed. To maintain a dedicated pressure in the main, is it best to...
Hello,
Trying to find data for typical viscosities for thickened waterworks sludges (2-3%d.s.) in order to check pressure drop in pump system. Sludge will be drawn off WRC thickener. WRC TR185 gives useful data for sewage sludge but haven't seen anything for waterworks sludge. Any help...
Looking at previous threads on numbers of jockey pumps, I agree that one jockey pump makes sense for pressurisation of the firemains. However I'm currently looking at the design of a new system that will require three, possibly four separate diesel driven firepumps and have picked up a clause in...
