Answer 1

dp/dx = const* q where q is the flow rate i.e.. changing with time

Answer 2

Ok dear ,, find the attach file

Answer 3

@jdoe0001 please

Answer 4

@tkhunny

Answer 5

How would you solve this one? \(\dfrac{d^{2}P}{dz^{2}} = \dfrac{dP}{dt}\)?

Answer 6

I can slove it using la place ,,, but here I think we have to used fouier cosine

Answer 7

also I think we have to solve each direction individual then combine the solution
