1.Water flows at 0.32 m^3/s through a 600-mm-diameter pipeline with a head loss of 0.0029 m/m. Find the value of the Hazen Williams coefficient.

2.Water is pumped from the large tank shown in Figure. The head loss is known to be equal to 5V^2/2g and the pump head is hp = 18 - 4Q^2, where hp is in ft when Q is in ft3/s. Determine the flowrate. Figure is an open tank leading to a horizonal pipe with area .10 ft^2 and height of 13 ft. Find Q.

3.Water leaves a turbine at 18.5 fps and enters a tailrace having an average velocity of 1.5 fps. What is the submerged discharge head loss? By what percentage is this loss reduced if the provision of a draft tube increases the discharge flow area to six times the size?
