pipe carrying oil of sp gr 0 877 changes in A pipe carrying oil of sp gr 0.877 changes in size from 150mm at section E to 450mm at section R Section E is 3 66m lower than R section R. Section E is 3.66m lower than R and the pressures are 91.0kPa and 60.3kPa, respectively. If the discharge is 0.146m3 respectively. If the discharge is 0.146m /s, determine the lost head and the direction of flow.

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°
