Q.37 Water is moving through a pipe. The velocity profile at a particular section is given mathematically as - (1) (²-²) 4μ 4 V = where v = velocity of water at any position r В = constant μ = viscosity of water d= pipe diameter r = radial distance from centreline of pipe (i) What is the shear stress at the wall of the pipe due to the water? (ii) What is the shear stress at a position r = d/4? (iii) If the given profile persists a distance L along the pipe, what drag is induced on the pipe by the water in the direction of flow over this distance?

Moments

There are various practical applications of the concept of moments, like a rotation of the crank due to linear motion of the piston, the moment of inertia and its use in designing beams and columns, bending moment concept, torque, twisting moment, etc.
