A wave is first reflected by a boundary P and then by a boundary Q without dissipating energy. If the boundary P is rigid and the boundary Q is non-rigid, then find the fraction of the amplitude of the reflected wave by boundary P to the reflected wave by boundary Q.
Consider the following statements.
1. A Computed Tomography (CT) scan uses X-rays to make detailed pictures.
2. A CT scan can be used to study all parts of Human body.
3. CT scan can help determine how much the cancer has spread in body. This is called staging the cancer.
Which of the statements given above is/are correct?
The nature of normal grain growth in the presence of a second phase deserves special consideration. The moving boundaries will be attached to the particles exert a pulling force on the boundary restricting its motion. Therefore if the boundary intersects the particle surface at 90° the particle will feel a pull of (2πrγcosΘ)*sinΘ. This will be counterbalanced by an equal and opposite force acting on the boundary. As the boundary moves over the particle surface Θ changes and the drag reaches a maximum value, this happens when Θ becomes______
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)

Given is the procedure for construction of flow net. Which of the following options is correct sequence of construction? 1. Sketch one flow line or one equipotential line adjacent to a boundary flow line or a boundary equipotential line. 2.
