water flows at a speed 5 cm/s through a pipe of radis 2cm .the viscosity of water is 0.001 pl.the reynolds number and nature of flow are respectively ??????????????????????

Two metal balls of radius R and 2R Falling through a fluid have same velocity at some point .the viscous drag acting on them at that instant are in the ratio ???????????????????

A fluid of density 2 into 10 raise to power cube kg/m cube is flowing in horizontal pipe .the speed of water at point A is 4cm/s ,what is its speed at point B (Height=2.5mm)

The pressure at a point in water is 10 N/m squre .the depth below this point where the presure becomes double is (given density of water = 10 cube kg/m cube ,g= 10 m/s square ?????????????????????????????????

On centigrade scale the temperature of a body increases by 30 degrees .The increase in temperature on fahrenheit scale is ???????????????????????????????????????????

A 1600 kg car moves along a horizontal road
at speed v0 = 17.3 m/s. The road is wet,
so the static friction coefficient between the
tires and the road is only μs = 0.311 and
the kinetic friction coefficient is even lower,
μk = 0.2177.
The acceleration of gravity is 9.8 m/s2 . Assume: No aerodynamic forces; g =
9.8 m/s2, forward is the positive direction.
What is the highest possible deceleration of
the car under such conditions?
Answer in units of m/s2
