What is a minor loss in fluid systems?

Challenge Problems
Push your limits with advanced challenges
A fluid flows through a pipe with an expansion from 50 mm to 100 mm diameter. The speed at the smaller diameter is 2 m/s. Calculate the k_l for this expansion if you determine it's appropriate to be 0.2.
💡 Hint: Use the principle of conservation to find outflow velocity first before calculating.
A system requires 0.5 meters of head loss due to minor losses from various fittings. If the total fluid velocity is 5 m/s, estimate the appropriate k_l value representing the entire system.
💡 Hint: Revisit your equations to ensure accuracy when rearranging for k_l.
