Unformatted text preview: MAE 3064 LAB 1 Properties of Fluids Syrus Jeanes Swapnil Adhav 9/3/2007 Abstract Determinations of several critical properties for a number of different fluids were made. The fluids used were water, vegetable oil and 10W-30 motor oil. Among the properties calculated were the specific gravity, density, viscosity and pressure. water = 1000 kg/m 3 Veg. Oil = 904 kg/m 3 Motor Oil = 1075 kg/m 3 SG water = 1.0 SG Veg. Oil = 0.92 SG Motor Oil = 0.88 veg 1 = 0.345 kg/m.s veg 2 = 0.254 kg/m.s motor 1 = 0.837 kg/m.s motor 2 = 0.709 kg/m.s falling = 9.562 kg/m.s Re = 0.0179 Table of Contents 1) Introduction 1 2) Theory 2-4 3) Experimental Facilities and Apparatus 5 4) Results 6-7 5) Statement of Uncertainty 8-10 6) Conclusion and References 11 1 Introduction This lab was a simple study of hydrostatics. Its purpose was to carry out experiments on a number of liquids in order to determine several, critical properties of said fluids. If engineering analyses were to be carried out involving these liquids, the properties obtained in this lab would be of the utmost importance. Density, being mass divided by volume is often the best and only way of quickly determining the weight of a volume of fluid. Viscosity is useful in figuring out the resistance to movement a fluid will give. Pressure levels are highly important in several day to day objects such as cars and aircraft. Understanding how to measure pressure using various means can be very useful. Theory Density The density bottle was used for calculating the density of the liquids. Once the mass was determined via a balance scale, the following equation was used: Volume water = 25 ml Volume oils = 50 ml Specific Gravity Using the densities calculated in part 1, the specific gravities were then obtained using a hydrometer and the following equation: = 998.2 kg/m 3 at 20 C ( Rounded to 1000 for engineering purposes ) It should also be noted that SG has no units. Viscosity A rotational viscometer was used to determine the viscosity of the oils as well as a falling ball viscometer. The following equation was used for the Couette Flow rotational viscometer: = Dynamic Viscosity r = Radius of Cylinder Pulley m = Pulling mass attached to line R = Outer Radius of Cylinder R i = Inner Radius of Cylinder L = Length of Cylinder U = Velocity of fall of the mass m The formula for the falling ball viscometer is:...
