(Solved): A 100 mm diameter suction pipe leading to a pump carries a discharge of 0.03 m3/s of oil (SG=0.85). ...
A 100 mm diameter suction pipe leading to a pump carries a discharge of 0.03 m3/s of oil (SG=0.85). If the pressure at point A in the suction pipe is vacuum of 180 mmHg, find the total energy head at point A in meters with respect to a datum at the pump. Use unit of water 9.79 kN/m^3 Oil Datum P 1.2m Oil A
Expert Answer
Given Diameter of pipe (D) = 100mm = 0.1m So, Area of pipe(A) = (?/4)0.12 = 0.007854 m2 Discharge (Q) = 0.03m3/s specific gravity of oil (SG) = 0.85 Pressure at point A = 180mm Hg we need to find total energy head at point A Assuming datum as show
