Mechanical Engineering Compressors, Gas Turbines And Jet Engines Difficulty: Medium

Moment of inertia of a circular section about an axis perpendicular to the section is The specific speed from 160 to 500 r.p.m. of a centrifugal pump indicates that the pump is According to Indian standard specifications, plain carbon steel designated by 40 C8 means that the carbon content is The sensible heat factor during the heating and humidification process is given by (where h 1 = Enthalpy of air entering the heating coil, h 2 = Enthalpy of air leaving the heating coil and h A = Enthalpy of air at the end of humidification process) In a 50% reaction turbine stage, tangential component of absolute velocity at rotor inlet is 537 m/s and the blade velocity is 454 m/s. The power output in kW of steam will be
