Water is pumped through an inclined pipe. The pressure, velocity, and datum at the pipe inlet are 9 bar, 15 m/s, and 1 m, respectively. The pressure, velocity, and datum at the pipe outlet are 3 bar, 20 m/s, and 4 m, respectively. Assuming g=10 m/s2 for convenience, determine the change in the Bernoulli head in m for this section of the pipe. The kinetic energy correction factors may be approximated as 1.0 for simplicity. Note: You don't need to write the unit with your answer. Write your answer to two decimal places
