2 pipe_03 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 =5.0*10-5 m is attached to a pump. Note that the kinematic viscosity of the water is =1.005*10-6 m 2 /s and the density is =1000 kg/m 3. a. If the pump is placed at the pit s surface (figure a), what is the maximum depth of the pit, H, for which water can be pumped out at a velocity of V=1 m/s without causing cavitation in the pipe? The vapor pressure of water for the current temperature is p v =2.337 kpa (absolute pressure) and atmospheric pressure is p atm =101 kpa (absolute pressure). b.
