GATE 2019 Engineering Sciences (XE-A, B, C, D, E, F, G, H) Question Paper and Answer key is given in the link below.
GATE 2019 XE - Engineering Sciences examination was conducted on 2nd Feb 2019.
Few Sample Questions from the Paper:
1. For stable equilibrium of a floating body, which one of the following statements is correct?
(A)Â Â Â Centre of gravity must be located below the centre of buoyancy.
(B)Â Â Â Centre of buoyancy must be located below the centre of gravity.
©Â Â Â metacentre must be located below the centre of gravity.
(D)Â Â Â Centre of gravity must be located below the metacentre.
2. A golf ball is dimpled to make the flow turbulent and consequently to reduce the drag. Turbulent flow reduces the drag on the golf ball because
(A)Â Â Â skin friction coefficient is lower in a turbulent flow.
(B)Â Â Â skin friction coefficient is higher in a turbulent flow.
©Â Â Â turbulent flow has a lower tendency to separate.
(D)Â Â Â turbulent flow has a higher tendency to separate.
3. For a steady laminar incompressible boundary layer flow over a sharp-edged flat plate at zero incidence,
(A)Â Â Â the edge of the boundary layer is a streamline.
(B)Â Â Â the edge of the boundary layer is a pathline.
©Â Â Â the skin friction coefficient decreases as the distance from the leading edge increases.
(D)Â Â Â the skin friction coefficient remains constant all along the plate.
