Tank 1 is full. Tanks 2 and 3 are completely empty. Water flows into tank 1 at a constant rate of PQ. Develop a model for the system.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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

Fluids at rest possess no flow energy. a)- true b)- false
