The efects of inlet air density on producedpower and heat rate are: A given engine design limits air volume fow capacity Produced power is a function of actual energy extracted per poundof vapor and mass fow of vapor For a given engine therefore, produced power varies directly with inlet air density Produced power does become limited by low volume (stall and surge) fowCare must be taken when selecting gas turbines to ensure sufcient shaft power is available at high temperature conditions and fouled inlet conditions, and gas turbine applications tend to be fully loaded since gas turbines (unlike steam turbines) are not custom designed.For a gas turbine, the vapor condition depends on the type of fuel used and the atmospheric conditions. This is because the inlet to the gas turbine engine is from the atmosphere, and any change in temperature, humidity or pressure will afect the mass fow into, and consequently thepower produced by the gas turbine. The gas turbine cycle (Brayton) is open.&.# Draw the %chematc -agram *(%mp!e ga% tur+nec)c!e wth nter c**!er . heat e'changer an- reheat,ANS:-HEAT EXCHANGERINTERCOOLERTREHEATQ3./hat % 0eat E'changer e((ect1ene%%,ANS:- The Number of Transfer Units (NTU) Meto! % u%e- t* ca!cu!ate the rate *( heat tran%(er n heat e'changer% (e%peca!!) c*unter current e'changer%" when there % n%u((cent n(*rmat*n t* ca!cu!ate the 2*g-Mean Temperature D((erence (2MTD".
