Can someone help me with chemistry?

<p>Hi. I'm doing a science project with viscosity. I'm using this formula: 2(delta P)ga^2/9V
delta P= the difference in density of the sphere and liquid.
g = the acceleration due to gravity
a^2 = the radius of the square
V= the average velocity</p>

<p>So for my first liquid I had 2(153.18)9.8 m/s^2 * 3^2/9(3.31) = 907.048</p>

<p>I just feel like I'm not doing this right. Is anyone familiar with this formula and can help. Or know a better formula for relative viscosity?</p>

<p>Check your units. “a” is in meters, and “V” is in meters/second. </p>

<p>Also, what kind of “relative viscosity” are you looking at?
There are plenty of formulas for types of viscosity.</p>
