- The height of the capillary rise of water increases as particle diameter increases True O False O Normal fault is generated by compressive force True O False O3. A solid cement rectangular lentil (beam) with length L = 1.5 m is positioned as shown. The lentil is fixed supported on its left hand side and simply supported on its right hand side leading to the mixed boundary conditions: embedded left y(0) = 0, y'(0) = 0 & simply supported right y(L) = 0, y'"(L) = 0 It is given that for this beam, E I = a. The lentil carries only its own uniform weight of w(x) = 240 N /m. Model the beam equation, representing it in terms of y'''. Use direct integration to determine the deflection y as a function of x. The order of your constants of integration as you integrate must be c1, c2, . . etc. LINTEL UNTEA pipe carrying water has average height of irregularities from the surface of the boundary as 0.15 mm. The shear stress developed is 4.9 N/m2 and the kinematic viscosity of water is .01 stokes. Calculate roughness Reynold number.
