![]() One figure showing relative viscosity with variations in pressure and temperature is also included.Ĭentipoise, gram/(centimetre second) = poise, kilogram/metre second =newton second/square metre = pascal second, pound/(foot hour) , pound/(foot second), reyn ![]() The figures and tables below shows how water viscosity changes with temperature (☌ and ☏) at water saturation pressure (which for practicle use, gives the same result as atmospheric pressure at temperatures < 100 ☌ (212☏)). See also dynamic and kinematic viscosity of air, ammonia, benzene, butane, carbon dioxide, ethane, ethanol, ethylene, methane, methanol, nitrogen, oxygen and propane.

See Water and Heavy Water - thermodynamic properties. Temperature Choose the actual unit of temperature: Note! Temperature must be within the ranges 0-370 ☌, 32-700 ☏, 273-645 K and 492-1160 °R to get valid values. While the kinematic viscosity is given as cSt, m 2/s, and ft 2/s The output dynamic viscosity is given as cP, mPa*s, Pa*s, N*s/m 2,lb f*s/ft 2 and lb m/(ft*h), The calculator below can be used to calculate the liquid water dynamic or kinematic viscosity at given temperatures. Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent. A ventilated environment is recommended during use.The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.įor further definitions, go to Absolute (dynamic) and kinematic viscosity. Meropa 220 gear lubricants have a typical sulfurphosphorus odor characteristic of industrial gear oils. Meropa gear lubricants 220 are suitable for use in Bijur oil application equipment. Meropa gear lubricants meet the requirements of: ![]() general industrial plant lubrication where the performance properties of an AGMA extreme pressure lubricant is required.bath, splash, circulating, or spray mist lubrication as applicable to the proper viscosity grade.industrial enclosed gearing where an AGMA extreme pressure lubricant is specified.Meropa gear lubricants are recommended for: Meropa gear lubricants are high performance, multipurpose gear lubricants designed for many types of industrial gear lubrication services where loads and shock loadings are high. Long oil life - Effective oxidation inhibitors and copper passivator minimize oil oxidation, limiting viscosity increase and promoting long drain intervals.The effective corrosion inhibitor provides additional protection for metal components. High thermal stability additive system minimizes the formation of high temperature compounds which can be corrosive to bearing materials. Good water separation and effective rust inhibitors protect surfaces against rust and corrosion. Long equipment life - Effective EP system forms a protective film in areas of metal-to-metal contact, minimizing wear rates and maintaining efficient transfer of power.High oxidation stability limits in-service viscosity increases, which can lead to energy losses. Gear set efficiencies - High thermal stability EP system helps maintain clean gear and bearing surfaces, minimizing deposits which interfere with effective lubrication.Meropa ISO 220 gear lubricants deliver value through:
