GATE ME 2012 | Question: 30
An incompressible fluid flows over a flat plate with zero pressure gradient. The boundary layer thickness is $1$ mm at a location where the Reynolds number is $1000$. If the velocity of the fluid alone is increased by a factor of $4$, then the boundary layer thickness at the same location, in mm will be $4$ $2$ $0.5$ $0.25$

GATE ME 2012 | Question: 17
The velocity triangles at the inlet and exit of the rotor of a turbomachine are shown. $V$ denotes the absolute velocity of the fluid, $W$ denotes the relative velocity of the fluid and $U$ denotes the blade velocity. Subscripts $1$ and $2$ refer to inlet and outlet respectively. If $V_2 =W_1$ and $V_1=W_2$, then the degree of reaction is $0$ $1$ $0.5$ $0.25$
