The pressure distribution of the naca0012 airfoil at zero angles of attack. airfoil equations can be found on the handout posted on blackboard or from online sources. compare its pressure distribution with the experimental data (find references) using a) 10, b) 20, and c) 100 panels equally distributed on both top and bottom side (that means twice the number of panels). comment on your results in the form of a report on

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
