1克/厘米·秒=1泊 3)cP(centipoise)厘泊,通常写作cps 4)dpa.s是decipascal-seconds缩写,一般用于高粘度表示。换算如下: 1Pa.s=1000mPa.s 1Pa.s=10poise 1poise=100cps 1cps=1mPa.s 1Pa.s=1000cps, 10dPa.s=1Pa.s 1dPa.s=100cps 在上面的模型中含有一个假定,就是剪力F与剪速S成线性关系,而...
Saybolt Universal Seconds (orSUS) is an alternative unit for measuring viscosity. The efflux time is Saybolt UniversalSeconds(SUS) required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Universal viscometer - under a carefully controlled temperature and...
How to convert pascal-seconds to centipoises [Pa·s to cP]: ηcP = 1 000 ×ηPa·s How many centipoises in a pascal-second:If ηPa·s = 1 then ηcP = 1 000 × 1 = 1 000 cP How many centipoises in 14 pascal-seconds:If ηPa·s = 14 then ηcP = 1 000 × 14 = 14...
Pascals can be combined with time (seconds) to define dynamic viscosity. μ = Pa•s 1.00 Pa•s = 10 Poise = 1000 Centipoise Centipoise (cP) is commonly used to describe dynamic viscosity because water at a temperature of 20°C has a viscosity of 1.002 Centipoise. This value must be ...
Cen tipoise (cP) is also a com mon unit for dyn amic viscosity 1 cP is the viscosity of water around room temperature. The imperial units, pound-seconds per square foot (lb*s/ftA2), are very seldom usedWhat is the diffire nce betwee n 6、kin ematic viscosity and dyn amic ...
As the fluid gets thicker - a function of its increasing resistance to flow - then it takes progressively longer to move through the tube (funnel). Water goes through in one second. The same amount of honey takes a thousand seconds (hypothetically). We know that if we raise and lower ...
that if a pressure of 1 Pa is applied for 1 second, the plate will move the same distance as the distance between the two plates. Centipoise (cP) is also a common unit for dynamic viscosity — 1 cP is the viscosity of water around room temperature. The imperial units, pound-seconds ...
Generally speaking, kinematic viscosity (cSt) relates to absolute viscosity (cP) as a function of the fluid’s specific gravity (SG) according to the equations in figure 3. Figure 3. Viscosity Equations As simple and elegant as these equations look, they hold true only for so-called Newtonian...
The results of this study suggest that solutions of up to 3 mL and up to 15–20 cP injected into the abdomen within 10 seconds are well tolerated without pain. High viscosity injections were shown to be the most tolerated, whereas injection volume and flow rates did not impact perceived ...
Therefore, for a crude oil with a specific gravity of 0.89 and dynamic viscosity μ = 38 cP, kinematic viscosity is calculated from Eq. (1.9) as ν=38/0.89=42.7 cSt. In the petroleum industry, two additional kinematic viscosity units for liquids are used. These are Saybolt Seconds Uni...
