A one stage axial air compressor consists of a rotor and a stator, it has a mean diameter of Im for the rotor and a rotational speed of 7645 RPM. Furthermore: Mass flow rate is 50 kg/s .Inlet static temperature and pressure of Ti 276 K and Pi 85 kPa. .Inlet stagnation temperature and pressure of Toi 290 K and Poi 101.3 kPa. .Inlet absolute velocity C1 166.5 m/s Rotor exit static density (p2) equals to 1.3kg/m3 Axial component of...
a twelve-bladed axial flow fan has a hydraulic efficiency of 0.92, mean radius of 0.93m and rotates at 450rpm. air enters the blades axially at a speed of 40m/s and the head developed across the blades is 35m of air. if the cord length at the mean radius is 0.33m, find the blade angles at inlet and outlet if the blades may be considered to act as isolated aero foils. if the blades are aero foils with the following characteristics,...
TQi The rotor and stator rows arrangement of an axial compressor stage and their general velocity diagrams are shown in Figure 1.1 (a) and (b), respectively. The compressor rotor blade speed is set at 100 m's and the inlet absolute flow velocity for rotor (C1) and stator (C:) are given in APPENDIX A (Each student will have different data) Consider normal stage condition and constant axial flow throughout the stage at 50 m's 01 C 0 SS 93 ROTOR t=100...
Q2 Figure 2.1 shows the velocity diagram for an axial turbine stage. The turbine rotor blade speed is 80 m's. Exhaust gas flow through the turbine stage with a constant axial velocity (2) at 90 m/s. List of relative and absolute flow angles at the rotor inlet and outlet are given in APPENDIX D for each student, respectively. At rotor inlet At rotor outlet B3 Cx2 = 90 m/s B2 Cx3 = 90 m/s W2 0.3 Cys 44 U =...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
