a mining engineer plans to do hydraulic mining with a high-speedjet of water. a lake is located H=300 m above the mine site Waterwill be delivered through L=900 m of hte fire house with an insidediameter D= 75 mm and relative roughness E/D=0.01. couplings , each with a loss coefficient of k=0.15, are located every 10 m along thehose. the nozzle outlet diamter is d= 25 mm, its minor losscoefficient is k=0.02 based on outlet velocity
estimate the maximum outlet velocity that this system could deliver.
