Consider a uniform flow of a liquid with density and viscosity equal to 760 kg/m³ and 0.05 Pa s past a rectangular plate with length of 1 m, width of 0.4 m and negligible thickness. The flow is parallel to its length and velocity is 2 m/s. (a) Determine the drag force on this plate. (b) The same plate is now subject to a uniform flow of another liquid with velocity parallel to its width. The density and viscosity of this liquid are 980 kg/m³ and 0.02 Pa s. Determine the uniform velocity so that the drag force is the same as (a).

Question
Transcribed Image Text:Consider a uniform flow of a liquid with density and viscosity equal to 760 kg/m³ and 0.05 Pa s
past a rectangular plate with length of 1 m, width of 0.4 m and negligible thickness. The flow is
parallel to its length and velocity is 2 m/s.
(a) Determine the drag force on this plate.
(b) The same plate is now subject to a uniform flow of another liquid with velocity parallel
to its width. The density and viscosity of this liquid are 980 kg/m³ and 0.02 Pa s.
Determine the uniform velocity so that the drag force is the same as (a).
