Water flows around a thin flat plate (0.25 m long, 2 m wide) with a free stream velocity (πβ) of 1 m/s, as shown in the figure. Consider linear velocity profile ( π’ πβ= π¦ πΏ) for which the laminar boundary layer thickness is expressed as πΏ= 3.5π₯ βπ ππ₯ . For water, density = 1000 kg/m3 and dynamic viscosity = 0.001 kg/m.s. Net drag force (in N, rounded off to two decimal places) acting on the plate, neglecting the end effects, is ________.
Answer: 1.10 to 1.20
