**Hey this problem of mine involves unsteady fluid flow (Q) into a cylinder of diameter (D). There is a small hole at the bottom of the cylinder of diameter (d) which is much smaller than (D) hence d << D. Because of this the fluid level will rise to a maximum height (h) before decreasing to zero over time.**

How does the unsteady fluid flow relate to the height? As in is it possible to work out this maximum height that would occur?

**I'm so stuck on this! Could anyone point me in the right direction? I understand that the work will not be done for me but if you could point me in the right direction with equations to use I would be very greatful.**
