Results:

Since the mass of the ball bearing employed in this research was incredibly light, 20 balls had been measured as well as the result was divided simply by 20 intended for better accuracy. This procedure was repeated for the sizes and the results are as follows: Diameter (mm)Mass (kg)

To find out the densities of the three golf balls, the following formula was used: Density= (mass in the ball)/(Volume from the ball)= mass/(4/3 π r^3 ) Denseness of 2mm ball sama dengan (0. 04⁄1000)/(4/3 π 〖(0. 001)〗^3 )=9551 kg/m^3 Thickness of 3 millimeter ball sama dengan (0. 075⁄1000)/(4/3 π 〖(0. 0015)〗^3 )=5305. 16 kg/m^3 Density of 3 mm ball = (0. 11⁄1000)/(4/3 π 〖(0. 0020)〗^3 )=3282. 57 kg/m^3 Accordingly, the average thickness of the three balls is:

Avarage Density= (9551+5305. 16+3282. 57)/3

Avarage density=6046. twenty four kg/m^3

The above mentioned result is usually summarized the following:

Castrol oil results:

Thickness of the the liquid Castrol was found simply by dividing it is mass over its volume at temp of 26℃ as follows: Density= (mass with the liquid)/(Volume of the liquid used)

Density of liquid= mass/volume= (24. 5g )/(25 ml)= 0. 98 g⁄ml =980 kg/m^3

The three balls were dropped into the the liquid containing Castrol oil by a noted distance of 0. 252 m plus the following data were noted: Castor olive oil

Half a dozen trials were conducted to measure the coming back the ball to reach towards the bottom of the container. Here i will discuss a sample computation done for 2 millimeter diameter. The typical time for (2mm) ball =(1. 62+1. 54+1. 60+1. 63+1. 55+1. 78)/6=1. 62 securities and exchange commission's Terminal Speed = Distance/(Time (avarge) ) = (0. 252 m)/(1. 62 s) =0. 155 m/s Consequently, viscosity was calculated depending on the following equation: Viscosity (μ)= (2 (ball density-liquid density) g*r^2)/(9 v_s ) Viscosity (μ)= (2 (ρ_p-ρ_f ) g*r^2)/(9 v_s )

Viscosity based on 2 mm= (2( 9551-980))/(9(0. 155))*9. 81*(0. 001)² μ= zero. 121 Ns/m^2

Similar calculation was followed pertaining to the additional two balls to find the viscosity and the answers are as follows: Size (mm)Viscosity (Ns/m^2)

A chart was drawn between the rectangular of the radius of the three balls and the terminal velocity to obtain the gradient. This lean was after that used to estimate the average viscosity for castor oil making use of the below equation. Viscosity (μ)=(2 )/9* g (ρ_p-ρ_f )*gradient

It could be noted the square of radius of the sphere is definitely directly proportionate to the velocity and the gradient of the collection found to be 0. 00002 Since the typical density with the Castrol oil found earlier was 6046. 24 kg/m^3, and based on the lean obtained from the graph, the typical velocity was found the following: Viscosity (μ)=(2 )/9* on the lookout for. 81 (6046. 24-980)*0. 00002

Avarage Viscosity=0. 221 Ns/m^2

Glycerol Effects

The same process followed previously for Castrol oil was adopted for glycerol plus the results are the following: Density of liquid= mass/volume= (31. six g )/(25 ml)= 1 . 268 g⁄ml =1268 kg/m^3
