- Homework Statement
- Use dimensional analysis to predict how the speed of sound (u) in a gas may be influenced by the gas pressure (p), gas density (r) and acceleration due to gravity (g).

- Relevant Equations
- u∝p^a r^b g^c

p = ML^-1T^-2

r= ML^-3

g=LT^-2

I've been going round in circle and am stuggling as maths is not my strong suit. Any ideas?

Up to the point where i equate the powers and then confuse myself, any help would be greatly appreciated.
