This process is experimental and the keywords may be updated as the learning algorithm improves. These keywords were added by machine and not by the authors. So only a viscosity coefficient with respect to pressure has been indicated. Dependence of viscosity of water on pressure is quite weak. Viscosity of various oils used as standards at various temperatures has been given. Viscosity temperature relationship has been discussed. A shortcoming of not taking into considering uncertainty calculated by type B method has also been pointed out. A small comment about this method has been offered. Kestin and Shankland arrived at the uncertainty value by taking the sum of component uncertainties and got the value 0.26 %. along with the estimated uncertainty, have been described in detail. The pioneer works of Roscoe and Bainbridge, Torklep and Oye, Kestin and Shankland and Berstad et al. Swindells measured the viscosity of water by measuring the pressure difference between the ends of a capillary for a known rate of flow. Swindells capillary viscometer has been described in detail. The work carried out at NBS (NIST) USA has been described. Hence measurement of its viscosity has been discussed in detail. Water is the primary standard of viscosity.
