Revision Notes on Flow of Liquids and Viscosity (3/3) Modified formula, η = [η0AT1/2]/[1+(S/T)] (b) Effect of pressure:- At low pressure, co-efficient of viscosity of a gas varies directly with pressure. Rate of flow of liquid through a liquid through a capillary tube of radius r and length l, V= πpr4/8ηl = p/(8ηl/ πr4) = p/R Here p is the pressure difference between two ends of the capillary and R is the fluid resistance. Accelerated fluid containers:- tan θ = ax/g If W be the weight of a body and U be the up thrust force of the liquid on the body then, (a) The body sinks in the liquid of W>U (b) The body floats just completely immersed if W=U Pressure exerted by a column of liquid of height h:- P = hρg Here, ρ is the density of liquid. Pressure at a point within the liquid:- P = P0 +hρg Here, P0 is the atmospheric pressure and h is the depth of point with respect to free surface of liquid.
