Question

Consider the smooth square 10-cm-by-10-cm duct in
Fig. P7.25. The fluid is air at 20°C and 1 atm, flowing at
V_avg = 24 m/s. It is desired to increase the pressure drop
over the 1-m length by adding sharp 8-mm-long flat
plates across the duct, as shown. (a) Estimate the pressure
drop if there are no plates. (b) Estimate how many
plates are needed to generate an additional 100 Pa of
pressure drop.
