Flushing

In all of the oil flushes that I have been involved in that has never been a question. I can imagine that if you are trying to attain a specific temperature at all points in a system you are in for a long drawn out flush.

The usual approach is to maintain the outlet of the pump or sump temperature at the desired temperature.

The length of the pipe is never specified as a limiter. It is the temperature and velocity of the oil that is maintained for an effective flushing (if I remember well you are supposed to go into the borderline near turbulent flow to be really effective)

Hi,

You do need to supply a lot more information e.g. do you want tp pump oil through the pipes or are you placing lengths of pipe in a hot oil bath?

If the first, then you will need to know several things e.g pump output - flow rate and max pressure; oil viscosity (which is temperature related); density, and pipe bore (internal diameter). All these questions are required as a minimum to be able to calculate the Reynolds number so as to achieve a turbulent flow.
