PROBLEM $1$

Water at $27$ C flows with a mean velocity of $1\frac{m}{s}$ through a $1000$ m long pipe of $0\mathrm{.}25$ m inside diameter.

a$)$ Determine the pressure drop over the pipe length and the corresponding pump power requirement, if the pipe surface s smooth

b$)$ If the pipe is made of cast iron and its surface is clean, determine the pressure drop and pump power requirement
