WebThe operating volume flow for selecting the fan would be 10000 x 1.55 = 15500 m3/h The pressure coefficient for air at 180 oC is approximately 1.55 according the chart. The correct pressure used in the manufacturing data sheet should be 500 x 1.55 = 775 Pa The power consumption according the manufacturing data is 4 kW. WebNote that the last term is identically equal to zero by conservation of mass. If the mass flow in and out of the propeller streamtube are the same (as we have defined), then the net mass flux into the rest of the control volume must also be zero. So we have: as we reasoned before.
