Which of the following is a dimensioning guideline? a. use the least number of dimensions needed. b. always dimension hidden lines. c. put dimensions inside of objects. d. line dimension numbers up in a row.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
