Q. The hydraulic conductivity (K) of an isotropic aquifer is 10 m/day. If the hydraulic head within the aquifer drops 4 m over a distance of 750 m, the groundwater flow velocity within the acquifer is.............m/day. (Up to third decimal place).

a) Develop an equation for the head (in ft) developed by the pump described by the chartas a function of flow rate (in gpm) when the pump uses a 9 ¾” impeller. b) Develop an equation for the pump efficiency as a function of flow rate (gpm) when the pump uses a 9 ¾” impeller.

A liquid of specific gravity of 1.75 flows in a 6 cm horizontal pipe. The total energy at certain point in the flow is 80 J/N (joules/newton). The elevation of the pipe above the fixed datum is 2.6 m. If the pressure is 75 kPa. Determine the power available at the specified point in kW.(WITH FREE BODY DIAGRAM) CHOICES: A.148.91 B.146.96  C.142.25 D.144.22
