Problem
Water flows through this sudden expansion. In the 100-m long inlet pipe, the friction factor is 0.2. In the 100-m long exit pipe, the friction factor is 0.3. The diameter ratio is 1:2. The inlet velocity is V1 = 5 m/s. The inlet pipe diameter is Di = 40 cm. 100 m 100 m 2. What are the magnitudes of the head loss for the inlet pipe, the expansion, and the exit pipe?
