Fluid of mechanics for Chemical Engineering

1) What are the effects of velocity based on pressure ((Inlet)) changes?
2) Look at the graphs and plots and discuss how is the flow goes when the velocity and viscosity changes? (attach the figures and discuss about each one plz)
3) Discuss what happens when the pressure (in) HIGHER than pressure (out). And pressure (out) HIGHER than pressure (in)?
4) How do we know if the result is reasonable or not? Include a discussion focusing on whether the results match your expectations/seem physical reasonable.
