Air with a mass flow rate of 2.5 kg/s enters a horizontal nozzle operating at steady state at 480 K, 350 kPa, and velocity of 5 m/s. At the exit, the temperature is 300 K and the velocity is 450 m/s. Using the ideal gas EGMN 204 Spring 2020 model for air with constant cp = 1.011 kJ/kg · K, determine: (a) the area at the inlet, in m2 . (b) the heat transfer to the nozzle from its surroundings, in kW

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
