Steam enters a turbine with a pressure of P1 = (5000 – 903) kPa, specific internal energy u1 = (3500 + 903) kJ/kg, mass flow rate of 7.5 kg/s and density of 1 = [1+ (903/1000)] kg/m3 Steam leaves at P2 = (2903) kPa with a density of 2 = 4.5 kg/m3 and a specific internal energy of u2 = (1000 + 2903) kJ/kg. Heat loss from the device by radiation is 50 kJ/kg. Neglecting the changes in kinetic and potential energies, determine the power produced by the system.

Please solve this question. Subject: Transportation engineering Problem No.2 Fillet Radius Problem (Airport Engineering) Determine the minimum lead-in and the radius of the fillet to maintain the cockpit over the centerline for an aircraft with a 200.4 ft wingspan (i.e. airplane design group V), a wheelbase of 90.5 ft, undercarriage width of 41.3 ft, and the distance between the main undercarriage and cockpit equal to 95.3 ft. The aircraft is moving between two parallel taxiways through a connecting taxiway which has a centerline perpendicular to the parallel taxiway. (Assume taxiway width is 75 ft, the minimum safety margin is 15 ft, centerline radius is 150 ft).
