In an air-standard brayton cycle the air enters the compressor at 100 kpa and 10°c, with a mass flow rate of 6 kg/s. the pressure leaving the compressor is 10 bar and the turbine inlet temperature is 1100°c. for k=1.4, calculate the compressor, turbine, and network as well as the thermal efficiency of the cycle.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
