and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance. Therefore the effect of viscosity can be neglected in the pitot. Secondly‚ the speed of the flow

Measuring the Viscosity of Motor Oil ME331 Laboratory Assignment #1 Prepared for: Prof. Sangeorzan Submitted by: Abstract An experiment was conducted to model the effect of temperature on the viscosity of motor oil and compare the results to commercial values established by the Society of Automotive Engineers (SAE) for SAE 30‚ SAE 40 and SAE 5W30. The viscosity of the oil sample at eight temperatures between 20 °C and 55 °C was determined using a rotary Brookfield DV-II+ viscometer

water molecules can incorporate themselves into the ionic crystal structure. Water‚ after all‚ has an oxygen atom with two lone pairs capable of behaving as a Lewis base; it bonds easily to metal ions as evidenced by complex ions in transition metal chemistry. The metal ions and the water molecules are bonded by dative coordinate bonds from the oxygen atom of the water. Therefore‚ Water of crystallization is water that is stoichiometrically bound into a crystal. Crystal salts containing water of crystallization

Viscosity Lab Report. CITY UNIVERITY LONDON SCHOOL OF ENGINEERING AND MATHEMATICAL SCIENCES 1. Abstract. In this experiment the viscosity of pure glycerol and a glycerol – water mixture are measured. At the end of the test it is apparent that glycerol is a near perfect Newtonian fluid and that it is more viscous than water. We also can appreciate how viscosity varies within a given temperature range. 2. Introduction. The purpose of this experiment was to find the viscosity of
