Ajet airplane is flying at 30,000 ft altitude at airspeed v0 = 825 ft/s. the ambient (freestream) conditions are p0 = 628.4 psf and t0 = 411.7 deg r. air enters the diffuser of a turbojet engine and then passes through the compressor. a temperature sensor at the diffuser entrance (station 1) tells us that the static temperature is t1 = 435 deg r. flow through the diffuser and compressor is adiabatic and frictionless. the inlet area (diffuser entrance) is a1 = 2 ft2 . the compressor raises the total pressure so that pt3/pt2 = 15.a) compute the airplane’s flight mach number (m0) and the mach number at the diffuser entrance, m1.b) compute the stagnation (total) temperatures at the entrance to the diffuser (station 1), entrance to the compressor (station 2), and exit of the compressor (station 3).c) compute the mass-flow rate through the diffuser and compressor.

Air enters a horizontal, constant-diameter heating duct operating at steady state at 290 k, 1 bar, with a volumetric flow rate of 0.25 m°/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k = 1.4 for the air, determine (a) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw flow rate, in kg/s, (b) the mass kg 0.3

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
