Datos utilizados:Este nmero de potencia es anlogo a un factor de friccin o un coeficiente de rozamiento
Donde P: Potencia consumidaNp: Numero de PotenciaEl nmero de Reynolds es un numero adimensional importante para determinar el nmero de potencia, se determina as
Donde : Densidad del fluido en Kg/m3: viscosidad del fluido Kg/m.sn: velocidad de giroDa: dimetro del impulsorMuestra de clculo.Para la muestra de clculo se tomara como base una agitacin con deflectores, se tomara la siguiente tabla:RPMTorque (lb-pulg)n (rev/s)Torque (kg-m)

densidad(Kg/m3)= 999.23
Da(m)= 0.0823
Para calcular el consumo de potencia terica se utilizar:
a) Calcularemos el nmero de Reynolds para saber si el flujo es turbulento o laminar con la siguiente relacin:
b) Luego se calculara el nmero de potencia , que depender del nmero de Reynolds
b.1) Para Re10000 (flujo turbulento), con placas deflectoras:
c) Se reemplazara el nmero de potencia, dependiendo del nmero de ReynoldsComo por ejemplo, para nuestro caso, cogeremos el primer valor de la tabla indicada:Hlice con bafle.1 Para una velocidad de N=0.8333 rev/s y un torque de =0.0253 kg-m.
2 Como el Re es mucho mayor que 10, el flujo ser aproximadamente turbulento (Np=KT).
Consumo de potencia experimental.1 Siguiendo la ecuacin que involucra a la potencia y al torque:
Para nuestro caso:
Clculo del NPo.Una vez obtenido el valor de la potencia experimental, calculamos el valor de Npo para obtener una grfica que muestre la correlacin de este nmero adimensional con el Re.
Para la hlice pequea con deflectores, de los clculos anteriores:
