Hey, good to see you again. To determine whether the flow is laminar or turbulent, we need to calculate the Reynolds number (Re). Step 1: Identify the given values and convert units. Specific gravity of oil (SG) = 0.9 Dynamic viscosity of oil () = 47.9 × 10^-3 \, Ns/m^2 (assuming Ns/m³ is a typo and should be Ns/m²) Pipe diameter (D) = 152 \, mm = 0.152 \, m Velocity of flow (V) = 0.60 \, m/s Density of water (_water) = 1000 \, kg/m^3 Step 2: Calculate the density of the oil (_oil). The specific gravity is the ratio of the fluid's density to the density of water. _oil = SG × _water _oil = 0.9 × 1000 \, kg/m^3 _oil = 900 \, kg/m^3 Step 3: Calculate the Reynolds number (Re). The formula for the Reynolds number is: Re = _oil V D Substitute the values: Re = (900 \, kg/m^3) × (0.60 \, m/s) × (0.152 \, m)47.9 × 10^-3 \, Ns/m^2 Re = 82.08 \, kg · m^-1 · s^-10.0479 \, Ns/m^2 Re = (82.08)/(0.0479) Re ≈ 1713.57 Step 4: Determine the type of flow. For flow in a pipe: • If Re < 2000, the flow is laminar. • If 2000 < Re < 4000, the flow is transitional. • If Re > 4000, the flow is turbulent. Since Re ≈ 1713.57, which is less than 2000, the flow is laminar. The flow is a laminar one. Laminar Send me the next one 📸
