Ammonia - Dynamic and Kinematic Viscosity vs. Temperature and Pressure
Online calculator, figures and tables showing dynamic (absolute) and kinematic viscosity of gasous and liquid ammonia at temperatures ranging from -73 to 425°C (-100 to 800°F) at pressure ranging from 1 to 1000 bara (14.5 - 14500 psia) - SI and Imperial Units.
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
For further definitions, go to Absolute (dynamic) and kinematic viscosity. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent.
Tabulated values and viscosity units conversion are given below the figures.
Online Ammonia Gas Viscosity Calculator
The calculator below can be used to calculate dynamic or kinematic viscosity of gaseous ammonia at given temperatures and atmospheric pressure.
The output dynamic viscosity is given as Pa*s, N*s/m2, cP, mPa*s, lbf*s/ft2 and lbm/(ft*h),
while the kinematic viscosity is given as cSt, m2/s, and ft2/s
Note! Temperature must be within the ranges -33 - 427 °C, -28 - 800 °F, 240 - 700 K and 432-1260 °R to get valid values.
