pls can anyone delete this topic?!?!

i have an equation i can't solve analitically. my goal is to find a simple solution for h(t) as a function of t, not an exact solution but a simple exponent of t will do i.e h is proportional to t^(alpha) i need to find that alpha. my equation is a simplified reynolds eq(based on lubrication approx) with b.c and i.c attached my methods are solving the eq for p and than for h since h does not depend on x. please help me!
