Water flows through a straight section of a 10 cm inner diameter cast-iron pipe with an average velocity of 0.1 m/s. The pipe is 30 m long, and there is an increase in elevation of 1 m from the inlet to the outlet of the pipe. a. Draw a flowchart for the system. Write the general energy balance and reduce it to the form where no terms are negligible. b. Assuming no kinetic energy losses due to friction, how much power does the pump add to the fluid
