Challenge Problems
Push your limits with advanced challenges
Calculate the pressure drop over a 10-meter length of 2 cm diameter pipe for a fluid with a Reynolds number of 1000. Assume viscosity of water at room temperature (0.001 Pa.s).
💡 Hint: Use 8 and convert diameter to meters for radius.
If the diameter of a pipe used to transport a viscous fluid is doubled, how does this affect the flow rate based on Poiseuille's Law?
💡 Hint: Review the relationship in the Poiseuille equation with respect to diameter.
