In air standard brayton cycle the air enters the compressor at 100 kpa, 300 k. the pressure at the end

compression process is 500 kpa and the maximum temperature in the cycle is limited to 1200 k. calculate (a)

the pressure and temperature at each point in the cycle, (b) the compressor work, the turbine work and cycle

efficiency. assume specific heats to be constant.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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
