Download Solution PDFCp and Cv for working fluid in a diesel cycle are 1 kJ/kgK and 0.718 kJ/kgK respectively. Temperatures at the beginning and the end of the heat addition process are 1473 K and 1723 K respectively. The heat added is:
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFConcept:
Heat addition in the diesel cycle is a constant pressure process.
Heat added (Q) = Cp × (T3 – T2) kJ/kg
Cp = Heat capacity at the constant process.
T2 = Temperature at the end of the heat addition process
T2 = Temperature at the beginning of the heat addition process
Calculation:
Given:
Cp = 1 kJ/kgk, T3 = 1723 K, T2 = 1473 K
Q = 1 × (1723 - 1473) = 250 kJ/kg
