Headloss in orifice

WebThe head loss of orifice meter is generally smaller than the rotameter but higher than the venturi meter. But the head losses and hence the energy losses increase with the increase in flow rate based on the result obtained for orifice meter. This constriction causes the formation of eddies downstream after the orifice plate resulting in energy ...
