Two systems of monotonic ideal gas are separated by a diathermal wall. In system A there are 2 moles initially at 175 K, in system B there are 3 moles initially at 400 K. Write U_AU A and U_BU B as functions of RR and the determine the common temperature (in Kelvin) after equilibrium is reached.

The common temperature after equilibrium is reached = 310K

Explanation:

The attachment shows U_AU A and U_BU B as functions of RR

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
