Flow rate and viscosity lab

And the volume flow rate's inversely proportional to the viscosity because the more viscous the fluid, the more it resists flowing, and the less meters cube you'll get per second and it's inversely proportional also to the length of the tube. Pump selection for laboratory scale fluid handling useful for tiny flow rates, generally used for microfluidics ideal for pumping high-viscosity fluids that will not flow well through a standard impeller type pump the oil pump in most automobile engines is a gear pump. Govern flow the physics of flow flow can be divided into 2 different types, laminar and turbulent a number of as the viscosity increases the flow decreases proportionally, therefore flow and viscosity are inversely proportional viscosity is represented as _ as flow rate increases, the bobbin rises up the flowmeter and the gap. I've decided to do this video for my chemistry project hope you enjoy it zuzu. Useful in solvent-based applications such as starch, paints, coating and epoxy, the m8b viscosity sensor features a sturdy measuring tube that supports tank depth of up to 72.

Where δp is the pressure drop, q is the volumic flow rate, r is the resistance to flow, l is the length of the channel, r radius of the channel, η is the dynamic fluid viscosity and x the distance in direction of flow. The flow rate by measuring the position of the float relative to the position of the tube by using the integral scale, which is calibrated from 15 to 10 litres/minute fluid mechanics lab experiment (4): flow measurement. Ech 4224l unit operations lab i fluid flow 1-5 let us discuss how one can determine flow rates q 1 and q 2 through the pipes 1 and 2 if the total flow rate q is known the mass balance for this system can be written as. Viscosity is a fundamental property that relates to the fluid behavior at flow it is essential to know the viscosity of the fluid at related shear rates, in order to control product flow during actual application (spraying, injecting, printing or simply high-speed flowing.

For shear-thinning products measuring viscosity at a single shear rate obviously only provides a tiny glimpse of the full picture - instead a “flow curve” of viscosity across a range of shear rates is far more meaningful, from which a viscosity value at a shear rate relevant to the process or product usage conditions can be read. View lab report - viscosity lab report from ce 320a at new jersey institute of technology experiment #1 viscosity of liquids ce 320 a group # 1 submitted by: nicole gonzalez-sitja introduction the theory viscosity is a measure of the resistance of the liquid to deform or flow under an applied stress. Dr w pezzaglia physics 2b lab, fall 2012 page 3 las positas college lab #12 fluid flow 2012nov07 3 d viscosity measured in weird units • viscosity of water at 20 °c is about 1 cp (centipoise. Viscosity races – investigating the flow of liquids april 23, 2012 by emma vanstone 21 comments it is so annoying when get to the end of a ketchup bottle and you have to keep banging to get that last bit out.

B) the flow rate and viscosity are connected because the viscosity of the fluid affects the flow rate if a fluid has a low viscosity, it means that there will be a high flow rate if a fluid has a high viscosity, it will have low flow rate. Because the flow-rate is governed by resistance of the oil flowing under gravity through the capillary tube, this test actually measures an oil’s kinematic viscosity the viscosity is typically reported in centistokes (cst), equivalent to mm2/s in si units, and is calculated from the time it takes oil to flow from the starting point to the. A laboratory experiment on inferring poiseuille’s law for undergraduate students tube, respectively, η is the viscosity of the fluid and p is the pressure difference between the flow rate q as a function of the difference of pressure p for tubes of r = 088 mm.

He volume flow rate poiseuille’s law: laminar flow of a newtonian fluid through a pipe volume flow rate q = dv/dt q = dv/dt 2r η l p 1 p 2 ∆p = p 1-p 2 q = dv = ∆p πr4 parabolic velocity profile p 1 p 2⇒pressure drop along pipe ⇒ energy dissipated (thermal) by friction between streamlines. Flow rates were measured using the volume-time method in this lab by filling a bucket to a given volume and timing the procedure you have three trials at each of four flow rates. A ‘laboratory flow meters’ article by trevor forster, titan enterprises ltd laboratory flow meters flow measurement in a typical laboratory or pilot plant poses some unusual problems. Viscosity of pure liquids and solutions 4591 words | 19 pages i introduction viscosity, η, is the resistance of a fluid to flow the units of viscosity could be poise, dyne-seccm2, gcm-s, n-sm2 or pa-s.

For such a system with a pipe radius of r, fluid viscosity η, distance between the two points along the pipe δx = x 2 – x 1, and the volumetric flow rate q, of the fluid, the pressure difference between the two points along the pipe δp is given by poiseuille’s equation (see . A viscometer, viscosity meter or rheometer is a measuring instrument used to determine a fluid's internal flow resistance or viscosity the term viscosity typically refers to shear viscosity, ie, how a material reacts to being sheared. 12) viscosity (viscosity will be discussed in a later lab this semester) the dynamic viscosity ( m ) for a fluid [ft/l 2 ] is the ratio of the shear stress ( t ) acting on a fluid to the resulting rate of angular strain, which is the velocity (v or u) gradient (dv/dy or du/dy) where y is the coordinate distance normal to the direction of flow. Viscosity and surface tension are two physical characteristics of a liquid viscosity is the measure of how resistant to flow a liquid is, while surface tension is defined as how resistant the surface of a liquid is to penetration.
