Question

Water at 20C in a D=10m H=2m aboveground swimming pool is to be emptied by unplugging a 3-cm-diamater, 30-m-long horizontal plastic pipe attached to the bottom of the pool. Determine the initial rate of discharge of water through the pipe and the time it will take to fully empty the swimming pool assuming the entrance to the pipe is well-rounded with negligible loss. Use the initial discharge velocity to estimate the friction factor and use the factor for the time estimation.

Answer 1

Answer:

Given that

Water at 20C in a D = 10 M H=2 m above ground swimming pool i to be emptied by unplugging 3 cm diameter , 30 m long horizontal plastic pipe attached to the  bottom of the pool.
