An orifice plate is usually used to provide a sharp, localised pressure drop, which is usually accompanied by a degree of downstream pressure recovery. This makes them ideal for flow measuring devices (strictly you use them to measure the delta-P, pressure drop across the orifice plate). For throttling or flow restriction it is more usual to use a restrictor (basically a piece of the pipe with a reduced flow area). Most decent books on fluid dynamics should cover how to treat orifice plates, restrictors etc. this includes aspects such as entry and exit pressure losses. The book "Internal Flow Systems" by D S Miller is a text I have used in the past.
