Unformatted text preview: d) What is the mass flow rate of the water in the channel? What is the relationship between average velocity and Umax? e) What is the drag force exerted by the water on the top and bottom walls in the CV ABCD? f) If the friction force on the side walls can be neglected because of their small area compared to the top and bottom walls, what is the net pressure force acting on CV ? g) What is the rate of volume expansion of this flow? Show by using the equation which represents the rate of volume expansion. h) Where would you observe this type of flow in practical engineering applications? Give one or two examples....
