****** 区 Q2: The flow rate of liquid through pipe is 0.342 m³/s and the head loss per 100 m of pipe is 8 m. what is the diameter of the pipe? Kinematic viscosity v= 2*10$ m²/s, p=950 kg/m³ and equivalent roughness (ks= 0.06).

How do I answer this question?

Velocity distribution of a fluid in a sliding plate viscometer is used to measure the viscosity of the fluid. The top plate is moving with force (F) with a constant velocity (V) as shown in the Figure below. Force (Ft)= 5 N, Velocity (V) = 10 m/s, Temperature = 100°F. Top plate (Area » Length = 0.1 m and width = 0.05 m spaced by 0.001 m) is moving and the bottom plate is stationary. Determine: The viscosity of the fluid. Which fluid is this? Is this fluid more, or less viscous than water? ● IN FLOW N-L

Water at temperature of 20 °C is flowing inside a straight, smooth pipe with flow rate of 0.05 m3/h . With which pipe diameter will the flow transition from laminar to turbulent? Kinematic viscosity of water at 20 °C is 1.005·10-6 m2/s. Round off the answer to one decimal digit in cm, but enter the answer without the unit.
