A radial flow machine has an impeller with inlet diameter D1= 0.025m, outlet diameter D2=0.077m, inlet blade angle β1=40º, outlet blade angle β2=10º, and N=950 rpm. The angle of attack at the inlet is 90º Neglect the effects of slip conditions and losses, and assuming the radial flow components of the absolute velocity are the same at the inlet and the outlet. Calculate the specific work of the machine in J/kg Is this machine a pump or a turbine?
