Challenge Problems
Push your limits with advanced challenges
Calculate the pressure drop in a 20-meter long horizontal pipe with a diameter of 50 mm carrying water at 15 m/s, with viscosity 0.001 Pa·s.
💡 Hint: Convert all units to consistent SI units before calculations.
If the specific gravity of a liquid is 0.95 and a 100 kg mass is collected in 5 seconds, find the pressure difference in a 10-meter pipe with 0.1 m diameter.
💡 Hint: Always reassess your values using specific gravities.
