Unformatted text preview: CHEE 3363---Fluid Mechanics Assignment 12 (Due on Monday, Nov. 24) Pro 8.70 Consider the pipe flow from the water tower of Example 8.7. After another 10 years the pipe roughness has increased such that the flow is fully turbulent and ? = 0.04 . Find by how much the flow rate is decreased. Pro 8.76 Water is pumped at the rate of 0.075 ? 3 from a reservoir 20 m above a pump to a free discharge 35 m above the pump. The pressure on the intake side of the pump is 150 kPa and the pressure on the discharge side is 450 kPa. All pipes are commercial steel of 15 cm diameter. Determine (a) the head supplied by the pump and (b) the total head loss between the pump and point of free discharge. Pro 8.83 The Moody diagram gives the Darcy friction factor, ? , in terms of Reynolds number and relative roughness. The ? ? ? for pipe flow is defined as ?...
