[/yy] + [/zz] - ∂p/∂x = 0;
∂u/∂x = 0;
∂p/∂x = constant
i tried separation of variables ...
Show us what you tried...
μ[uyy + uzz] - ∂p/∂x = 0 ... (1)
∂u/∂x = 0 ;
now i assumed u(y,z) = Y(y)Z(z)
so (1) becomes ... μ[ZYyy + YZzz] - ∂p/∂x = 0
hence (1/Y)*Yyy + (1/Z)*Zzz = (R/YZ) = -λ2
where, R = (1/μ)*∂p/∂x
now Yyy + λ2Y = 0 ... can be solved easily but what about the remaining part .... i couldn't solve it due to the constant
