It’s mainly a solvent for ingredients that do not like to dissolve in oils but rather in water. Once inside the skin, it hydrates, but not from the outside - putting pure water on the skin (hello long baths!) is drying.

Units, as in Nm3/s which means "Normal m3/s". Standard and Normal conditions for our choked flow calculation are 15 oC (i.e. 288.15 K, 59 oF, 518.67 oR) and 1 atm (i.e. 101,325 N/m2, 14.696 psia) from Perry (1984, p. 3-167). Some industries use different temperature and pressure for standard (or Normal) conditions. To convert the mass flow rate computed by our choked flow calculation to volumetric flow at a different Ts and Ps, use our gas flow conversions page. If gage pressure units are selected, the calculation assumes atmospheric pressure is Ps. The program uses Ps to convert between gage and absolute pressures.

Definition and conversion dynamic to kinematic viscosity Follow us on Twitter Question, remark ? Contact us at contact@myengineeringtools.com 1. Dynamic viscosity 2. Kinematic viscosity The viscosity is one of the fundamental properties of fluid used in almost every physical calculations, for example pressure drop calculation. This page is giving the definitions of 2 viscosity, dynamic and kinematic, and how to convert from one viscosity to another. 1. Dynamic viscosity The dynamic viscosity, often represented by the greek letter μ is a measure of the molecular interactions in the fluid. It is expressed in : Pa.s mPa.s cP (centipoise) It is possible to convert from unit to another thanks to : 1 cP = 1 mPa.s = 0.001 Pa.s 2. Kinematic viscosity The kinematic viscosity, often represented by the greek letter ν and used mainly for liquids, is a measure of the viscosity in the particular situation where the fluid is flowing down because of its own weight. Such a flow is actually dependent on the dynamic viscosity of the fluid but also its weight, represented by the density. The conversion from dynamic viscosity to kinematic viscosity can thus be done thanks to the following formula : ν = μ / ρ With : ν = kinematic viscosity (m2/s) μ = dynamic viscosity (Pa.s = kg/m.s) ρ = fluid density (kg/m3) The kinematic viscosity is measured in St (Stokes) cSt m2/s mm2/s The relation in between each unit is : 1 St = 10-4 m2/s 1 cSt = 0.01 St 1 cSt = 1 mm2/s AD AD -->.

The determination of the viscosity index is based on two oil types with the same starting viscosity and strongly diverging changes in viscosity as temperature rises. The oil showing a strong temperature dependence is assigned the viscosity index 0, whereas the oil with a lower change in viscosity is assigned the viscosity index 100. The viscosity index according to DIN 2909 is calculated by comparing the change in viscosity of an oil with the two oils as a reference. Viscosity Index of lubricants The viscosity of oils and base oils of lubricating greases from Klüber Lubrication can be determined by means of the known kinematic viscosity at 40 °C and 100 °C. The higher the viscosity index, the lower the viscosity change of an oil at fluctuating temperatures. A high viscosity index ensures consistent lubricating properties across a wide temperature range. The calculations on this website are based on general experience and knowledge acc. to DIN 2909 at the time of publication and are for information only. The information does not constitute any statement as to specifications, assurance of properties/warranties or the suitability of products for specific applications. All information is subject to change and does not claim to be exhaustive, correct or accurate. Klüber products are continually improved.

The jacket or coil design and the flow regime of the service fluid. Fletcher (1987) provides some useful guidance and the research club, HTFS has also produced a design report for members. The following correlations are recommended:Conventional unbaffled jacket, liquid service with high flow [(Lehrer (1970)](6)where:(7)vi is the velocity at the inlet nozzle or branch and vB is the velocity component due to buoyancy, Dj is the jacket diameter and DT is the vessel diameter.(8)whereis the volumetric flow rate, di is the diameter of the inlet, z is the wetted height of the jacket, β is the fluid thermal expansion coefficient, and ΔTs is the temperature rise of the service fluid. VA is the rise velocity in the jacket annulus and depends on the inlet orientation:(9)Conventional unbaffled jacket, liquid service with high flow [(Lehrer (1970)] (see also Free Convection)(10)Here,K = 0.15 for upward flow, heating; downward flow cooling;K = 0.128 for downward flow heating; upward flow cooling;ΔTm is the mean temperature difference between the service and the vessel wall(11)Baffled or dimpled jacket, liquid service. The service side coefficient for a baffled or dimpled jacket will be greater than for an unbaffled jacket with high flow, therefore the above can be used as a conservative estimate. Using the correlation for a half-pipe coil with the flow area equivalent to the baffle channel is not recommended as it may give an overestimate.Half-pipe coil, liquid service(12)This is the normal Sieder-Tate equation, (see Forced Convective Heat Transfer) applied to the whole jacketed area with the effectiveness factor (E) from Kneale (1969), typically 0.8–1. Nu and Re are based on the hydraulic mean diameter, de:(13)Condensing service. A condensing coefficient in a jacket should be extremely high compared to the process side and normally αs−1 ~ 0. A conservative estimate can be obtained from the Nusselt analysis [see Kern (1950)]:(14)The physical properties refer to the liquid phase and ΔT = Tsat - Twall (see Condensation).Process side heat transfer coefficientThe process side coefficient will be determined by the agitator type and speed. (See also Agitation Devices.) For low viscosity fluids, most turbine-type high-speed agitators can give good performance. For high viscosity and Non-Newtonian Fluids, larger diameter agitators will be required. Harnby et al. (1985) and Oldshue (1983) provide guidance on agitator selection. For Non-Newtonian Fluids, there are two important considerations:A mean apparent viscosity is required to calculate Nu from Re. The normal practice is to estimate it using the Metzner-Otto approach, where:(15)Kmo depends on the agitator type, N is the rotational speed (s -1).The viscosity correction only allows for the effect of temperature near the wall and NOT the distribution of shear rate. It will normally be sufficient to assume an homogeneous distribution of shear rate. Calculation.
