Challenge Problems
Push your limits with advanced challenges
A fluid of specific gravity 0.9 and viscosity 0.6 Pa·s flows through a 100mm diameter pipe. Calculate the average velocity if the flow rate is 0.1 m³/s.
💡 Hint: You need to derive the area from the diameter first.
Determine the pressure drop across a 25m length of pipe with viscosity of 0.8 Pa·s and experiencing an average flow velocity of 0.5 m/s, with the diameter given as 50mm.
💡 Hint: Look to apply the Darcy-Weisbach equation if familiar.
