Example for Application of Mass Balance A2=0.01 V2=8 m/s A3=0.06 m2 V3=? A1=0.05 m2 V1=4 m/s 60 degrees
Example for Application of Mass Balance Consider the steady flow in water pipe joint shown in the diagram. The areas are: A1=0.2 m2, A2=0.2 m2, and A3=0.15 m2. In addition, fluid is lost out of a hole at 4, estimated at a rate of 0.1 m3/s. The average speeds at sections 1 and 3 are V1=5 m/s and V3=12 m/s, respectively. Find the velocity at section 2.
Example for Application of Momentum Balance Required: Calculate the net rate of momentum Out through the control surface. A2=0.01 V2=8 m/s A3=0.06 m2 V3=? A1=0.05 m2 V1=4 m/s 60 degrees
