Water has a critical specific volume of 0.003155m3/kg. A closed and rigid steel
tank of volume 0.025m3 contains a mixture of water and steam at 0.1MPa. The
mass of the mixture is 10 kg. The tank is now slowly heated. The liquid level inside
the tank
Consider an incompressible laminar boundary layer flow over a flat plate of length
L, aligned with the direction of an incoming uniform free stream. If F is the ratio
of the drag force on the front half of the plate to the drag force on the rear half,
then
Consider steady laminar incompressible anti-symmetric fully developed viscous
flow through a straight circular pipe of constant cross-sectional area at a Reynolds
number of 5. The ratio of inertia force to viscous force on a fluid particle is
A ball bearing operating at a load F has 8000 hours of life. The life of the bearing,
in hours, when the load is doubled to 2F is

In orthogonal turning of a low carbon steel bar of diameter 150 mm with uncoated
carbide tool, the cutting velocity is 90 m/min. The feed is 0.24 mm/rev and the
depth of cut is 2mm. The chip thickness obtained is 0.48 mm. If the orthogonal
rake angle is zero and the principle cutting edge angle is 90c, the shear angle in
degree is
