Challenge Problems
Push your limits with challenges.
Question 1
In a pipeline, the orifice has a Cd value of 0.75. Calculate the flow rate if the diameter is 6 cm, the height of the fluid is 10 m, and the cross-sectional area equals 28.27 cm².
💡 Hint: Remember to convert values where necessary for uniformity.
Question 2
A pressurized tank has an orifice diameter of 12 cm and oil with a density of 850 kg/m³ flows through. If the pressure difference across the orifice is 3000 Pa, find Q assuming Cd is 0.9.
💡 Hint: Make sure to pay attention to unit conversions.
