check the validity (wrong or correct) of the following equations using

dimensional analysis:

a) t2 = 2x/a

b) t = x/v

c) a = v/x

d) v = a/t

ALSO ,

The term 1/2 PV^2

rv2 occurs in Bernoulli’s equation in Chapter 15,

with P being the density of a fluid and v its speed. Find the dimensions of

1/2 PV^2

Thank you in advance .

**bobpursley**, Saturday, October 2, 2010 at 4:32pmon the first, I will be happy to critique your thinking.

on the second

Pressure*velocity^2=force/area * distance^2/time^2=

force/time^2

but in second p mean density so the formula should be p=m/v m mass , v volume is not it ?

(M/L^3) x (L^2/T^2) = M/LT = ML^-1T^-2
