Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Where, ρ is the density of the fluid and Vavg is the average velocity of the fluid in the pipe and D is the diameter of the pipe and μ is the dynamic viscosity of the fluid
Calculation:
Given,
Specific gravity of oil = 0.8, thus density = 0.8 × 1000 = 800 kg/m3
Reynolds number = 2100, Dynamic viscosity = 8 × 10-3 Ns/m2,
Diameter = 100 mm = 100 × 10-3 m
