Problem

An ideal gas is taken through a cyclic thermodynamic process in four steps. The heat exchanged in these steps is Q1=5960 JQ_1=5960\,\mathrm{J}, Q2=−5585 JQ_2=-5585\,\mathrm{J}, Q3=−2980 JQ_3=-2980\,\mathrm{J}, and Q4=3645 JQ_4=3645\,\mathrm{J}, respectively. The corresponding work done by the gas is W1=2200 JW_1=2200\,\mathrm{J}, W2=−825 JW_2=-825\,\mathrm{J}, W3=−1100 JW_3=-1100\,\mathrm{J}, and W4W_4, respectively. (a) Find the value of W4W_4. (b) What is the efficiency of the cycle?
