Thermodynamics - Internally reversivble process

Hi everyone,

just created my account so this is my first post. I'm from Portugal and I'm studying Mechanical Engineering in FEUP.

So my doubt basically is about internally and externally reversible processes.

"Water is on a pipe with constant diameter initially at 50 ºC 7000kPa, and in the end of the pipe at 450ºC 6000kPa. Can this process be considered internally reversible? Why?"

Thanks

Welcome to PF Bruno!

Could you reverse the temperature and pressure gradient in the pipe by changing the initial conditions by an infinitesimal amount?
