The head loss in 80 m of 12 cm diameter pipes is 8 m when oil (s.g. = 0.9) of viscosity of 0.04 N-s/m2 flows at 0.05 m3/s. Determine the Reynolds number?

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 2.

The pipe bend shown is in a horizontal plane. Oil with a specific gravity of 0.86 enters the reducing bend at section A with a velocity of 3.2 m/s and a pressure of 150 kPa. Neglecting head loss, determine (a) The velocity at section B, V3 (m/s) (b) The pressure at section B, ps (kPa) (c) FMx (N) de = 100 mm B da = 150 mm 30°
