Pick out the wrong statement?
AExistence of the boundary layer in fluid flow is because of viscosity of the fluid.
BAn ideal fluid is the one, which has negligible surface tension and obeys the Newton’s law of viscosity
CThe shear stress at any given cross-section of a pipe for steady flow (either laminar or turbulent) varies linearly as the radial distance
DThe form drag is dependent upon the occurrence of a wake
Correct answer
B. An ideal fluid is the one, which has negligible surface tension and obeys the Newton’s law of viscosity
Explanation
The correct answer is An ideal fluid is the one, which has negligible surface tension and obeys the Newton’s law of viscosity.
