Agas in a piston–cylinder assembly undergoes a compression process for which the relation between pressure and volume is given by p = av-1 + bv (p is in bar and v is in m3 ). the initial volume is 0.1 m3 , and the initial pressure is 1 bar. the final volume is 0.04 m3 , and the final pressure is 2 bar. determine: (a) the values of a and b (b) the work for the process, in kj

Fluids at rest possess no flow energy. a)- true b)- false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Which of the following components of a pid controlled accumulates the error over time and responds to system error after the error has been accumulated? a)- proportional b)- derivative c)- integral d)- on/off.
