Example: B/3
Task:
Comparative Diesel cycleoperates with
air as a working material (ideal gas).
specific heat constant of air is r= 287 J.kq ¹.K 1. specific
heat capacity of air (volume is constant) is 717.5 J.kg ¹.K¹,
ration of specific heat is, k = 1.4.
Compression ration in this cycle is 18 and cut off ration is 2.
Before compression is pressure 100 kPa(a) and temperature 25 °C.
Heat rejected from this cycle is
350.6 kJ/kg.
Calculete:
a) Pressures and Temperatures in the main points of this
cycle
b) Heat input to this cycle for 1kg of working material
Draw This cycle in p-v diagram, describe all thermodynamic
processes in this cycle
and mark in this cycle heat input and heat rejected.
