![A large cylindrical tank with diameter D is firmly mounted on a wagon. Water flows out of the
tank through a nozzle with circular cross section and diameter d (d << D). The height of the
water level above the nozzle centerline is defined by h, and the initial height is he. The flow can
be assumed to be i -free.

a) Calculate the water level h(t) as a function of time as well as g. D and d
if h(t = 0) ho applies.
Calculate the time it takes the tank to empty (h = 0).
Determine the thrust force acting on the wagon at time = 5s. For this purpose, draw
an appropriate control volume. Note: If you could not solve part a), usev = √pgh.
