If a fitting in a duct decreasesthe flow area in the direction of airflow by 3-times, then what is the related change in velocity pressure? Assuming no friction, what is the related change intotal and static pressures?

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
