Any buddy, please provide me the GATE Model Papers for Mechanical Engineering………..

This is the GATE Model Papers for Mechanical Engineering:

Q.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
(A) 4 (B) 2 (C) 0.5 (D) 0.25

Q.31 A room contains 35 kg of dry air and 0.5 kg of water vapor. The total pressure and temperature of
air in the room are 100 kPa and 25°C respectively. Given that the saturation pressure for water at
25°C is 3.17 kPa, the relative humidity of the air in the room is
(A) 67% (B) 55% (C) 83% (D) 71%
