The modulus of subgrade reaction is obtained from the plate bearing test in the form of load-deformation curve. The pressure corresponding to the following settlement value should be used for computing modulus of subgrade reaction
X-component of velocity in a 2-D incompressible flow is given by u = y^{2} + 4 xy. If Y-com-ponent of velocity 'v' equals zero at y = 0, the expression for 'v' is given by
