3. Find the minimum diameter of a smooth tube to ensure the flow of water at an average velocity of 100 cm/s remains turbulent. Use vwater = 1E-6 m²/s. [Ans.: 4 mm]. %3D

Freshwater (density = 1000 kg/m³, viscosity cm diameter tube with an average velocity of 0.23 m/s. What is the Reynold's number of the flow (first blank)? Is the flow laminar, transitional, or turbulent (second blank)? = 0.001 kg/(m*s)) is flowing through a 2 Blank # 1 Blank # 2

Water at 25˚C is flowing past a long cylinder at a velocity of 1.2 m/s in a large tunnel. Theaxis of the cylinder is perpendicular to the direction of flow. The diameter of the cylinder is0.12 m. What is the force per meter length on the cylinder

A smooth pipe (30 cm) diameter and (100m) long has flush entrance and submerged discharge. The velocity is (3m/sec).If the fluid water ,what is the total hen loss? Take ( e=0.00026 cm, K,-0.5 ,K-1.0) If the water replaced by the oil with kinematics viscosity (9.3 *10 m'/sec and s -0.925 ). Determine the pressure loss.
