ASE 362K Problem Set #4 Clemens / Spring 2010 Due: Friday, February 26 Problem 1. Anderson Prob. 3.8 Problem 2. Anderson Prob. 3.11 Problem 3. Air at the stagnation state (P 0 =1.2 atm and T 0 =300 K) enters a frictionless constant- area duct with a cross-sectional area of 5 cm 2 . The air enters at a velocity u 1 =100 m/s. If the heat added is 500 kJ/kg then determine: (i) the mass flow rate through the duct (ii) the exit temperature and Mach number

Unformatted text preview: Problem 4. Air at static conditions of 300 K and 1 atm enters a straight frictionless duct that is 5 inches in diameter. The flow rate through the pipe is 1 kg/s. Heat is transferred to the air in the pipe and the exit pressure is 0.5 atm. (i) Determine the rate of heat added in watts. (ii) Determine the rate of entropy transfer to the gas [in units of J/K/sec]. P 1 = 1atm T 1 =300K ܳ ሶ [W] P 2 =0.5 atm...
