centrifugal blower is designed to draw 28m^3/min of carbon dioxide at 32C and 21 kPa gage and compresses it to 35 Kpa gage when operating at 4000 rpm. It is to be tested with air at 101.325 kPa and 21 C and driven by a motor at running at 3550 rpm. Determine the flow rate which the machine should deliver at design point on test to be acceptable. Overal

Superheated steam at 40 bar absolute and 500°C flows at a rate of 250 kg/min to an adiabaticturbine, where it expands to 5 bar. The turbine develops 1500 kW. From the turbine thesteam flows to a heater, where it is reheated isobarically to its initial temperature. Neglectkinetic energy changes.(a) Write an energy balance on the turbine and use it to determine the outlet streamtemperature.(b) Write an energy balance on the heater and use it to determine the required input (kW) tothe steam.(c) Verify that an overall energy balance on the two-unit process is satisfied.(d) Suppose the turbine inlet and outlet pipes both have diameters of 0.5 meter. Show that itis reasonable to neglect the change in kinetic energy for this unit.
