Problem $2.$ Chapter $9(20$ points$)$ Cannot apply Bernoulli, finding pressure within the pipe means Pressure B is not $0.$

Castor oil is flowing from A to B through a pipe with a diameter of $30$ mm at a flow rate of $0\mathrm{.}003\frac{m^3}{s}$

a$)$ Determine the Reynold's Number.

b$)$ Determine the change in pressure between A and B $.$

c$)$ Determine the shear stress on the wall of the pipe based on that pressure drop.
