Since you know the mach number at the inlet and static pressure u can go for pressure inlet. In pressure inlet it will ask for two pressures, one is gauge total pressure (it can be calculated from mach no. and pressure isentropic relation), the other one is (supersonic/initial gauge pressure) there u need to give static pressure relative to operating pressure (i.e. static preesure minus operating pressure).
