Estimate the change in enthalpy and entropy when liquid ammonia at 270 k is com- pressed from its saturation pressure of 381 kpa to 1200 kpa. for saturated liquid ammonia at 270 k, v = 1.551 x 10-3 mkg-1, and f = 2.095 x 10-'ki

your parents i think this could be it

i think so it’s will be b yes i believe its

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.
