Water is being transported through a horizontal rough pipe $(\frac{u_t{}_p}{v})=(100$ long, with maximum velocity $2\mathrm{.}5\frac{m}{s}.$ If the Reynold's Number of flow is ${10}^6,$ find the diameter of the pip and horsepower required to maintain the flow. Pwater $=1000k\frac{g}{m^3}$

viscosity$=1\mathrm{.}02{10}^{-6}\frac{m^2}{s}$
