Extracted text: 10. A thin flat plate ( 45 cm X 90 cm ) is immersed in a stream of glycerin (p = 1258 kg/m' and u = 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: 1/2 Cplam = 1.328 / Re Cpturb = 0.072 / Re eeri
