A square plate 0.1 m side moves parallel to second plate with a velocity of 0.1 , both plates being immersed in water. If the viscous force is 0.002 N and the coefficient of viscosity 0.001 poise, distance between the plates isQuestion 2
A container of large uniform cross sectional area A resting on a horizontal surface holds two immiscible non viscous and incompressible liquids of density d and 3d, each of height H/2.The lower density liquid is open to the atmosphere having pressure ,. A tiny hole of area a(a<<A) is punched to the vertical side of lower container at a height h (0<h<H/2) for which range is maximum.Stuck on the question or explanation?
