Class XI 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 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 The specific gravity of a material is the ratio of its mass to the mass of water the ratio of its volume to the density of water the ratio of its density to the density of water the ratio of its mass to the density of water Density is defined as volume per unit mass volume of 10 kg of the material volume of 1 kg of the material mass per unit volume 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?
