The article attached provides mathematical formulations that ought to be obtained analytically as mathematical derivations of the equations provided (section 2.2 unsteady state only) equations 5a - 5l.
Also the last sentence of the last paragraph of section 2.2 says that the w and p can be found from equation equation 1k and consequently obtained u from equation 5m.
Tasks:
Obtain formulas from section 2.2: 5a - 5l
Obtain formulas for: w and p using equation 1k
Obtain the formula for: u using equation 5m
Provide a step by step formulations so I can understand i.e. detailed approach of the equations.
