Consider an airplane with two jet engines. Each engine expels combustion gases at a rate of 14 kg/s. For engine A the gases exit at a velocity of 310 m/s, and for engine B they exit at 295 m/s. The momentum flux correction factor for the exit of each engine is 1.14. The total thrust in N is closest to 5337 8470 239 9656

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Find the kinematic pressure of 160kpa. for air, r-287 j/ kg k. and hair al viscosity of air at a temperature of 50°c and an absolute (10 points) (b) find the dynamic viscosity of air at 110 °c. sutherland constant for air is 111k

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
