A pipe transporting water undergoes a sudden expansion. If the upstream pressure is 200 kPa and the mass ?ux is 40 kg=s, ?nd the pressure downstream, where a uniform ?ow can be assumed, and the head lost due to the expansion. Use the following dimensions:
(a) d1 ¼ 4 cm and d2 ¼ 10 cm
(b) d1 ¼ 4 cm and d2 ¼ 8 cm
(c) d1 ¼ 6 cm and d2 ¼ 12 cm
