    Pump Start-up and steady state heat transfer model

    I get the feeling that I may have offended Mr. Racookpe1978, I apologise for being vague. I don't want YOU to do it for me, I want to do it myself and all I am asking for is some help as to where to begin and what I need to consider (apart from what I mentioned). I haven't really dealt with...

    Pump Start-up and steady state heat transfer model

    Hi everyone, I am trying to model the start-up and steady state heat transfer for a steam jacketed pump which is used to pump bitumen. The bitumen is solid in the pump and the steam enters the jackets and heats up the bitumen via conduction. This makes it more complicated because the...

    Steam Jacket Viscosity Reduction Calculations

    Hi everyone, I'm looking to determine the time it takes for the viscosity of the pumpage to reduce to a suitable level to allow the pump to operate freely. The pump in question is a CP13 PP26 (API674 Direct Acting Recip.) The pump end has been fitted with steam jackets. I have limited...
