Is it possible that cavitations occurs on orifices in H-pipe?
If yes what is the area ratio of area of orifice to the area of pipe ?

    Yes, cavitation can occur on the downstream side of an orifice. Whether it does or not depends not on the ratio of the area of the orifice to the pipe, but on the volume of flow through the pipe, the area of the orifice, and the absolute pressure head of the water upstream. Those factors will determine the absolute pressure head of the water immediately downstream of the orifice; if that is less than the vapour pressure of the water at that temperature, you will get cavitation.
