###### Question details

Problem 1 (20 pts.)

a) (10 pts.) A 30-cm diameter pipe conveys water at the rate of 106 L/sec. Determine the contraction head loss if the diameter is suddenly reduced to 15 cm. Compare this with the head loss incurred when the 15-cm pipe suddenly expands to 30 cm.

b) (10 pts.) With the same flow rate and geometry, determine the corresponding head losses (in % of the originally calculated in a) if a 15° confusor and a 15° diffuser are used to reduce the head losses
