Q. 11 Check by dimension analysis whether the following equations are correct(i) v =, where P is Pressure and pis density

Answer»

V = velocity has dimension of LT-¹

and pressure = F/A has dimension of ML-¹T-²

and density = M/V has dimension of ML-³

so, pressure/density = L²T-²and √(pressure/density) = LT-¹

which is same as Velocity , hence ✓
