Consider the following figure. P (MPa) 7 6 5 4 3 2 1 0 i 2 4 6 8 V(m³) (a) Determine the work done on a fluid that expands from i to f as indicated in the figure. -12.3 X Your response differs from the correct answer by more than 10%. Double check your calculations. MJ (b) How much work is done on the fluid if it is compressed from f to i along the same path? 12.3 X Your response differs from the correct answer by more than 10%. Double check your calculations. MJ
