The results of the validated experiment show that the theoretical values calculated employing the modified equation exhibit better agreement with the experimental values, particularly when the viscosities of two‐phase fluid are great. The results of the modified two‐phase relative p...
It is an object of this invention to provide a two component polyurethane adhesive having the following combination of physical and performance properties: Individual components with low enough viscosities so that these can be mixed rapidly by using impingement mixing, molecular mixing or meter mixing...
Another permittivity and another viscosity of the engine oil are determined, during the usage of the engine oil, and a carbon black content (2) in the engine oil is determined based on a difference between the two permittivities and a difference between the two viscosities. The two permit...
The dimensionless parameters that play a key role to define the flow properties are the ratio between the viscous and capillary forces, referred to as the capillary number, and the ratio between the viscosities of the two fluids. Depending on the values of these param- eters, the flow ...
Here qw and qs are the water and steam mass flow rates, krw and krs the water and steam relative permeabilities and υw and υs the kinematic viscosities of water and steam, respectively. Note that 0 ≤ krw and krs ≤ 1. By defining the kinematic viscosity of the water/steam mixture ...
Here subscripts o and w refer to oil and water phases, λt is the total mobility, with λt=λo+λw, where λo=kro/μo and λw=krw/μw, kro and krw are relative permeability to the oil and water phases respectively, and μo and μw are phase viscosities. Additional variables are...
Most of the piping systems in the oil and gas, chemical, and process industries are subjected to two-phase flow, especially liquid and gas. Based on the diameter and inclination of the pipe, and liquid and gas flow rates, various types of flow regimes occur in the pipe. One can find th...
However, the difference between acidizing curves of different viscosities is not obvious in general, as shown in Fig. 17. Neither for the least PVTB and optimum acid injection velocity. But it is worth noting that the discussion between viscosity and PVTB here are under the assumption that the...
Further, for the purpose of adjusting viscosities of both pastes to the same extent to improve a mixing property, an organic solvent may be contained as a viscosity adjusting agent.Examples of such the organic solvent are not limited to, but include alcohols such as methanol, ethanol, 1-...
The flow of a powder coating composition is dependent on various factors, including, without limitation, the viscosity of the binder resin(s), oil absorption of extender pigments, flow control agents, the ratio of extender pigments to resin used in the composition, the reactivity of the resin,...
