Water flows steadily through a pipe of length L and radius R=75mm. The velocity distribution across the outlet is given by u=umax 1− r2 R2 and umax =3m=s. Evaluate the ratio of the x-direction momentum flux at the pipe outlet to that at the inlet.

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
