Power (watt) of a shaft is a function of mass flow rate (k(g)/(s)), velocity ((m)/(s)), specific heat capacity ((J)/(k)g.K), temperature change (K) of the liquid and height increase (m);W^(˙)= f((m^(˙)),C_(p),Delta T,z,V). For water C_(p)=4.18k(J)/(k)g.K. The following data is reported for water flow rate of 7.5k(g)/(s) and velocity 3.5(m)/(s), elevation or height increase 1m. a) Find dimensionless power and dimensionless temperature change groups. (15 pts) b) Plot dimensionless power versus dimensionless temperature change, and suggest a suitable fit.
