Question

For each of the following, find its dimensionsin terms of primary dimensions only.
a.) Volume Flow Rate

b.) Mass Flow Rate

c.) Density

d.) Electrical Voltage (Hint: Electrical Power in a circuit isvoltage times current, and current is one the seven primarydimensions.)

e.) Electrical Resistance (Hint: Use Ohm's Law)


THANKS ! You can submit your answers in different parts soyou can get more points. Help with any or all them would begreat! I really don't get Dimensional Analysis for somereason :-(

Explanation / Answer

We already know V is M L^2 / (C Th^2) And I is measured in amperes, which is C/Th
So V/I would be L^2 M / (Th C^2)
Hope that helps
