AB  - The rheological parameters of 5 edible vegetable oils have been determined. In particular: rapeseed oil, corn oil, sunflower oil, olive oil and pumpkin oil. The oils exhibited Newtonian behaviour above about 10 s<sup>-1</sup>. The lower rates of shear demonstreated non-Newtonian behaviour. The analysed oils were found to be, in accordance with predictions, time-independent. The flow curves of all tested oils have been plotted and fitted in satisfying agreement with simple mathematical model. Received data have been used for numerical simulation of inlet effect in laminar flow between two parallel plates. The simulation of velocities and fluid pressure have been created.
