Find the temperature drop and pressureratioacrossthe LP turbine, taking the temperature into itascalculated in Exercise 5.1, and then the temperature and pressureatoutlet from the LPturbine.Assumeabypassratio(i.e. the ratio of themassflow of the bypassstreamtothemassflowthroughthecore) equal to 6.Takethepressureratioandefficiencyacrossthe fan for the bypass flow to be 1.6 and90%(asfor the fan flow goingthroughthe core).
