Q= Fluid mechanics question.

Water flows in a horizontal rectangular channel. The water depth is 0.3 m and the flow speed is 0.5 m/s uniformly over the depth. Then the flow passes over a smooth bump on the channel floor and it is observed that the water depth above the peak of the bump is 0.25 m. Neglecting friction, calculate the height of the bump.

Hi anyone i need help on this question , i know that v1=v2= 0.5m/s , and z1= 0.3 and z2=0.25h , when i find h i get 0.05 m which is wrong!
