The velocity profile for a thin film of a Newtonian fluid that is confined (4mm) between the plate and a fixed surface is defined by u=(10y-0.25y2 ) mm/s where y is in mm. Determine the force P that must be applied to the plate to cause this motion. The plate has a surface area of 5000mm2 in contact with the fluid. Take µ= 0.532 N. s/m2 (

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i. e., a violation of one statement leads to the violatio the other statement)

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
