The electric force experienced by charge q B is 8 N (1 C = 10 -6 C and k = 9.10 9 N.m 2 .C -2 ).As an engineering practice or R&D leader, you continuously improve how you solve complex problems to remain competitive and sustainable. Thermodynamic Processes States of a thermodynamic system can be changed by interacting with its surrounding through work and heat. Most test questions can be Ideally, which fluid can do more work: air at 600 psia and 600F or steam at 600 psia and 600F Solution: The maximum work a substance can do is given by its availablity. 7-4-1 [tmax-2000C] An ideal cold air standard Diesel cycle has a compression ratio of 20. So the net work done is negative, implying that the work done on the system is greater than the work done by the system. Adiabatic Process: It is a thermodynamic process in which no heat is exchanged between the system and the surrounding.
