Water enters through one end of a horizontal pipe of non-uniform cross – InterviewSolution

InterviewSolution

1.	Water enters through one end of a horizontal pipe of non-uniform cross-section with a velocity of 0.4 m/s and leaves the other end with a velocity 0.6 m/s. The pressure of water at the entry point is 1500 N/m2. What is the pressure at the exit point? (Density of water =1.0×103 kg/m3)
Answer» Water enters through one end of a horizontal pipe of non-uniform cross-section with a velocity of $0.4 m/s$ and leaves the other end with a velocity $0.6 m/s$ . The pressure of water at the entry point is $1500 {N/m}^{2}$ . What is the pressure at the exit point? (Density of water $= 1.0 \times 10^{3} {kg/m}^{3})$
