Water flows steadily through a rectangular pipe with width 0.4 m and height 0.6 m. The pipe is 150 m long and horizontal. Water enters the pipe from a large open reservoir with a water surface elevation of 12 m above the pipe outlet at a velocity of 1.5 m/s. The pipe discharges freely into the atmosphere. Neglect minor losses. Using the energy equation, determine: a. The head loss due to friction in the rectangular pipe. b. If the rectangular pipe is replaced with a circular pipe of diameter 0.5 m and the same length, determine the velocity of water at the pipe outlet
