Class XI Flow is said to be steady if the flow rate decreases 10%% every second the flow rate increases with time the flow rate does not change with time the flow rate decreases 20%% every second Pressure p at any point in a fluid at rest is the normal force at that point per unit area the normal force at that point per unit mass the normal force at that point per unit volume the force parallel to area at that point per unit area in laminar flow adjacent layers of fluid move in circle crossing each other each other and the flow is steady adjacent layers of fluid slide smoothly past each other and the flow is unsteady adjacent layers of fluid do not slide smoothly past each other and the flow is unsteady adjacent layers of fluid slide smoothly past each other and the flow is steady If a pipe carrying incompressible liquid has an area A1A1 and velocity V1V1 at one point A2A2 and V2V2 at another point, the equation of continuity gives the relation A1V1=A2V2 A1V1=2A2V2 A1V1=3A2V2 A1V1=2A2V The pressure at a depth of h in a fluid of density ρρ at a place where the acceleration due to gravity is g and the pressure at h=0 is p0p0 is given by p = p0p0 + 2ρ2ρ gh p = p0p0+ 3ρ3ρ gh p = ρρ gh p = p0p0 + ρρ gh Do you really want to submit this quiz?
