please Help me with my homework please :( and show and explain how you go there answer and why?

4. The height of the free surface, 4, in a tank of diameter, D, that is draining fluid through a small hole at the bottom with diameter, d, decreases with time, . This change in free surface height is studied experimentally with a half-scale model. For the prototype tank: H =16 in. (the initial height of the free surface) D=4.0in. d=0.251n. Experimental data is obtained from the prototype and half-scale model and is given below: Model Data Prototype Data h [in. t[s h [in. 8.0 0.0 16.0 7.0 3l 14.0 6.0 6.2 12.0 5.0 9.9 10.0 4.0 13.5 8.0 3.0 18.1 6.0 2.0 24.0 4.0 1.0 325 2.0 0.0 43.0 0.0 tls 0.0 4.5 8.9 14.0 202 259 328 45.7 59.8 hole with diameter, d Plot, on the same graph. the height data as a function of time for both the model and the prototype. Develop a set of dimensionless parameters for this problem assuming that: h = f(H.
