```1. The compression ratio of an air powered diesel cycle is A = 18 and the cutting ratio is B = 2.2. The pressure of the air at the beginning of the compression process is C = 94 kPa and the temperature is D = 32 ° C. Considering that the specific temperatures change with temperature (using the air standard, not the cold air standard only, that is, using the relative specific volumes from the table) and accepting the gas constant of the air as 0.287 kJ / kg K
a-) Find the temperature at the end of the compression (T2), the temperature at the end of the heat treatment (T3) and the temperature at the end of the expansion (T4) in the K unit. (15 p)
b-) Calculate the thermal efficiency of the cycle. (15 p)
c-) Calculate the average effective pressure of the cycle in kPa. (10 p)```

NOTE:Don't used cp and cv.
