TL;DR: In this paper, the kinematics of fluid flow in the measuring unit of a rotational viscometer with variation in the rotational velocity by the exponential law has been considered, and the asymptotic expression for calculation of the rate of shear and the dimensionless parameter determining the regime of steady-state flow have been obtained.
Abstract: The kinematics of fluid flow in the measuring unit of a rotational viscometer with variation in the rotational velocity by the exponential law has been considered. The asymptotic expression for calculation of the rate of shear and the dimensionless parameter determining the regime of steady-state flow have been obtained. Experimental check of this method has been carried out. It has been shown that exponential variation in the rotational velocity of the measuring unit makes it possible to cut the time of measurement of the flow curve and to improve the accuracy of measurement in the region of low shear rates.

TL;DR: In this paper, a simple viscometer consisting of a trink straw and a mineral water bottle was used to predict the vicosity of water and a model was derived from Bernoulli's principle and Poiseulli's law.
Abstract: A simple viscometer consists of mineral water bottle and trink straw is used to predict vicosity of water. A model is derived from Bernoulli's principle and Poiseulli's law. Value about 0.374 - 0.707 cP is obtained for observation in room temperature. About 10 minutes of observation time is needed to get the data.
Keywords: equation of continuity, Bernoulli's equation, viscosity coefficient, Poiseulli flow.

TL;DR: In this paper, the viscometer includes a container, an overflow pipe, and a flowmeter, and the filling height in the container is maintained at a constant height, which is dependent only on the viscosity.
Abstract: The viscometer includes a container (1), an overflow pipe (2), and a flowmeter (3). The filling height in the container is maintained at a constant height. The flowmeter measures the flow value which is dependent only on the viscosity. Hence it is possible to infer the viscosity directly from the flow speed.
TL;DR: The c-myc protein in normal tissue-Effects of fixation on its apparent subcellular distribution and the role of nuclear oncogenes in transformation and nuclear localisation are studied.
