A Power Plant In Kerteh Terengganu Operates On The Simple Brayton Cycle By Using Air As The Working Fluid Has A Pressur 1 (43.68 KiB) Viewed 25 times

A power plant in Kerteh, Terengganu operates on the Simple Brayton cycle by using air as the working fluid has a pressure ratio of 7. The minimum and maximum temperatures in the cycle are 310 K and 1150 K, respectively. If the compressor works at 75% isentropic efficiency whereas the turbine is at 82%, sketch the process on a T-s diagram and determine: (a) the air temperature at the turbine exit, (b) the net-work output, and (c) the thermal efficiency After a while, the operation manager decided to employ energy recovery practice, and therefore regenerative modification is made to the existing power plant above. If the effectiveness of the regenerative is only 65%, sketch the new process on a T-s diagram and determine the new thermal efficiency of the cycle.
