It rains during the construction of a building and water fills a recently excavated pit to a depth, h=0.5m. in order to continue construction, the water must first be pumped out of the pit. a hose with a length of l=50m, a diameter of d=2.5*10-2 m, and a surface roughness of e=5.0*10-5 m is attached to a pump. note that the kinematic viscosity of the water is n=1.005*10-6 m2 /s and the density is r=1000 kg/m3 .
