A thin flat plate ( 45 cm X 90 cm ) is immersed in a stream of glycerin ( ρ = 1258 kg/m3 and μ = 1.49 Pa.s ) with a velocity of ( 7 m/s ). Compute the skin frictional ( viscous ) drag exerted on the upper surface of the plate, if : a) The plate side parallel to the stream is the shortest side b) The plate side parallel to the stream is the longest side You may use the following relations: CDlam = 1.328 / ReL^(1/2) CDturb = 0.072 / ReL^(1/5)

Question
A thin flat plate ( 45 cm X 90 cm ) is immersed in a stream of glycerin
( ρ = 1258 kg/m3 and μ = 1.49 Pa.s ) with a velocity of ( 7 m/s ). Compute the
skin frictional ( viscous ) drag exerted on the upper surface of the plate, if :
a) The plate side parallel to the stream is the shortest side
b) The plate side parallel to the stream is the longest side
You may use the following relations:
CDlam = 1.328 / ReL^(1/2)
CDturb = 0.072 / ReL^(1/5)
