The depth of water below the piezometric level is 30 m and it falls 2 m in the well while pumping. Calculate the discharge from the well when the radius of the circle of influence is 50 m.6. Crude oil of relative density 0.91 (viscosity 1.24 poise) is pumped through a supply pipeline 75 mm diameter, where a flow of 420 litres/min takes place between pipeline section 1.25 km from the feeder reservoir, and section 1.60 km from the feeder reservoir.
