Challenge Problems
Push your limits with advanced challenges
A fluid flows through a pipe with a diameter of 0.5 m, at a velocity of 3 m/s. Its dynamic viscosity is 0.001 Pa·s. Calculate the Reynolds number and determine the flow type.
💡 Hint: Ensure to check your density and units.
Determine the required power in watts to overcome the drag forces on a vehicle with a drag coefficient of 0.3, frontal area of 2.2 m², traveling at 90 km/h.
💡 Hint: Convert the velocity to m/s and find density for the calculations.
