he diagram shown illustrates the flow in a circular metal duct 20 feet long. The duct has a sudden contraction at the inlet and sudden expansion at the outlet. The diameter of the duct is 10 inches and the flow rate is 600 cfm. The duct is such that both ends have area ratio of 0.6. Thus A2/A1 = A3/A4 = 0.6. Calculate: (a) Pressure loss in the duct due to sudden contraction (in. wg.).

Question

The diagram shown illustrates the flow in a circular metal duct 20 feet long. The duct has
a sudden contraction at the inlet and sudden expansion at the outlet. The diameter of the
duct is 10 inches and the flow rate is 600 cfm. The duct is such that both ends have area
ratio of 0.6. Thus A2/A1 =
A3/A4 = 0.6. Calculate:
(a) Pressure loss in the
duct due to sudden
contraction (in. wg.).
