An open concrete aqueduct has a rectangular cross-section. The aqueduct is 10 ftwide and falls 10.5 ft in elevation for each mile of length. It is to carry 150,000 gpm of waterat 60 °F. If fF = 0.0049, what is the minimum depth needed if the aqueduct is not to overflow?[~ 4.3 ft]

1. Three reservoir A, B, and C are connected by pipelines 1, 2, 3 respectively which merges at a junction X. the elevation of reservoir A is 300 m and that of B is 285 m. The rate of flow from reservoir A is 1.4m³/s A) Compute the rate of flow in reservoir B B) Compute the rate of flow in reservoir C C) Compute the elevation of reservoir C EL 300 m Qb = 0.189 m³/s (receiver) Qc =1.211 m/s ELC = 148.93 m EL 285 m.

Answer as fast as possible, use 3 decimal

a horizontal 24" pipeline carries oil of sp gr. 0.825 flowing at a rate of 15.7 cfs. Each of four pumps required along the line is the same, i.e., the pressure on the suction side and on the discharge side will be -8.0 psi and +350 psi, respectively. If the lost head at the discharge stated is 6.0 ft for each 1000 ft of pipe, how far apart may pumps be placed? Ans. 167,000 ft
