- The resultant upward pressure of the fluid on an immersed body is called
- Which of the following meters is not associated with viscosity
- Due to each end contraction, the discharge of rectangular sharp crested weir is reduced by
- The process of diffusion of one liquid into the other through a semi-permeable membrane is called
- The boundary layer thickness at a distance of l m from the leading edge of a flat plate, kept at zero angle of incidence to the flow direction, is O.l cm. The velocity outside the boundary layer is 25 ml sec. The boundary layer thickness at a distance of 4 m is (Assume that boundary layer is entirely laminar)
