Consider fluid flowing through a circular pipe of constant radius as illustrated above. The figure is not to scale. The pipe diameter D = 0.2 m and length L = 8 m Consider the inlet velocity to be constant over the cross-section and equal to 1 m/s. The pressure at the pipe outlet is 1 atm. Take density ρ = 1 kg/ m ³ and coefficient of viscosity µ = 2 x 10 ^-3 kg/(m s). These parameters have been chosen to get a desired Reynolds number of 100 and don't correspond to any real fluid. 

Solve this problem numerically using ANSYS FLUENT. Present the following results:

• Velocity vectors 
• Velocity magnitude contours 
• Pressure contours 
• Velocity profile at the outlet
• Skin friction coefficient along the wall
