Select gas:Temperature:Viscosity:© 2013 LMNO Engineering,Research, and Software, Ltd.www.LMNOeng.comUnits in gas viscosity calculation:oC=degrees Celsius, K=Kelvin, oF=degrees Fahrenheit, oR=degreesRankine, lb-s/ft 2=pound-second per square foot, slug/ft-s=slug per foot persecond, N-s/m 2=Newton-second per square meter, kg/m-s=kilogram per meter persecond, SG=specific gravityThe viscosity on this page is the dynamic (absolute) viscosity. Dynamicviscosity of gases is primarily a function of temperature. This variation isprovided in Crane (1988) as a graph for hydrocarbon vapors and natural gases, and as anequation for other common gases. The impact of pressure is minor and the viscositycorrection for pressure is less than 10% for the gases in our calculation for pressures upto 500 psi (34.5 bar) (Crane, 1988).Hydrocarbon vapors and natural gasesThe LMNO Engineering calculation takes the user input temperature and extracts viscosityfrom the graph on page A-5 in Crane (1988), performing linear interpolation ifneeded.
The input temperature is restricted to the range 0.
Viscosity and Specific Gravity of LiquidsViscosity - Property of a liquid that resists any force tending to produce flow. It is the evidence of cohesion between the particles of a fluid which causes a liquid to offer resistance analogous to friction. An increase in the temperature usually reduces the viscosity; conversely, a temperature reduction usually increases the viscosity. Pipe friction loss increases as viscosity increases.Specific Gravity - Direct ratio of any liquid's weight to the weight of water at 62 degrees F. Water at 62 degrees F weighs 8.33 pounds per gallon and is designated 1.0 sp. Gr.The specific gravity of a liquid does not alter the centrifugal pump curve at all. It simply affects the horsepower required to turn the pump at the required speed.
Kinematic viscosity conversion calculator converts stoke, square meter per second, centistokes, square foot per hour vice versa with metric conversion. Kinematic viscosity is a measure of the resistive flow of a fluid under the influence of. That the viscosity of gases is roughly independent of pressure and density.
Correcting for HP requirements for liquids with a specific gravity other than 1.0 is calculated usingBHP = GPM X Head X Specific Gravity / 3960 x Pump Eff. Viscosity Conversion TableEffects of Viscosity - Viscous liquids tend to increase pump HP, reduce efficiency, reduce capacity and head and increase pipe friction.
