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. A piezometer records a pressure of 12425 Pa at the section D. Taking head loss due to friction into consideration as per viscous flow or turbulent flow prevailing, evaluate the pressure head at section.
