Expression for Pressure exerted by gas

Let N number of molecules of an ideal gas of mass M, be enclosed in a cubical base of sides L. Let i^th molecule move with velocity C_i , (see figure 1) and u_i , v_i , w_i be its X, Y, Z components.

Consider only X-component of motion of i^th molecule, then the force exerted by i^th molecule, on account of its periodic collisions at with front wall and change in its momentum of -2mu _i is

\ Force on front wall by all 'N' molecules

\ Pressure on front wall is
