If a is acceleration, v is velocity, x is position, and t is time, then
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

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
