Dimensional Analysis

Question

In formula P = (nRT)/(v - b) e-a/RTV. Find dimensions of a and b where P = pressure, n = no. of moles, T = temperature, V = volume and R = Universal Gas constant.

Ramesh V · Accepted Answer

P is pressure in N/m2 dimensional formula is : ML-1T-2 n is dimension less dimesnion of temperature represented by the Greek letter theta is q a/RTV shld be dimension less whihc means a has dimesnions same as RTV dimesnion of a is :ML5T-2 b has dimensions same as volume i.e, m3 or L3 so, dimesnion of a is :ML5T-2 dimesnion of b is : L3 -- Please feel free to post as many doubts on our disucssion forum as you can.

. Because of the rotation of the earth, a plumb bob may not hang exactly along the direction of
the earth’s gravitational pull (its weight) but deviates slightly from this direction. Calculate the
