• There are many reports available about the centrifugal-head flow meter but a few for its application. There upon we measured the discharge coefficient for seven (360??) centrifugalhead flow meters which were different in size in the range of R_s=10^2?`10^5. We obtained a simplified formula which expressed the relation between the discharge and the head as follows : For the range 4?~10^2<R_s<4.7?~10^4. Q=A {0.26+0.28 (B+log??h>)-0.03 (B+log??h>)^2}??h> (cm^3/sec) For the range 4.7?~10^4<R_s. Q=0.91??2gh>r_1??r_1R>??h>(cm^3/sec)
