- The geometry of the fixed and moving parts of the pump by way of the output from one or more solid-modelling packages of standard format
- the material(s) of which it will be constructed;
- the gaseous and liquid materials which will pass through the pumps;
- the rotation speed of the impeller;
- the pressures and temperatures of the gaseous and liquid materials at their inlets to the pump;
- the pressures prevailing at the outlets to the pump for gas and liquid;
- What will be the time-average torque which must be applied to the impeller shaft;
- What will be the time-average distribution of liquid concentration, gas concentration, pressure, temperature and velocity components within the pump [‘distribution’ means ‘values prevailing at all positions in three-dimensional space].
- qualitative understanding of the processes which occur in the pump by visual observation of three-dimensional transient representations on the computer screen.
