Lower or equal to the process liquid pressure, it is known as: select one: 1. flush fluid 2. buffer fluid 3. barrier fluid 4. quench fluid

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet
