The work produced by a constant temperature, pressure- volume thermodynamic process
can be computed as
W = ∫ p dv
Where W is work, p is pressure and V is volume. Using a combination of the trapezoidal rule,
Simpson’s 1/3 rule, and Simpson’s 3/8 rule, use the following data to compute the work in kJ
(kJ=kN.m)
