A centrifugal pump (not a vaccum pump) when fully filled with liquid is able to produce a certain negative pressure (vaccuum) at succion line. How can I determine this vaccum?
If the succion line is connected to a tank with no vent line, and the pump is turn on it's possible to collapse the...
In our plant we have a distillation tower (column A) whose energy is provided by a thermosifon reboiler which is fed with steam at 6,5 Kgf/cm² g .
The column A bottom temperature is kept at 90ºC ( pressure 0.2 kgf/cm² g). Bottom flow rate is 2200 kg/h ( enthalpy of vaporization is around 80...
I need to know how to compute the total time to completely empty a truck tank (by gravity flow). This tank is a cilindrical one and has in its bottom a nozzle of 3 inches, connected to a 3" diameter pipe with total lentgh of 10 meters (it's in horizontal). The pipe discharges to atmosphere and...
Very trick problem with pump
In the company I work for there's a centrifugal pump for pure acetic acid unloading from a truck tanker. The pump data is 60 m3/h x 60m. Since the flowrate is a little bit high, when the tank is almost empty (i.e. when acid level in container has dropped)...
