6) 5 points: The energy and hydraulic grade lines experience discrete jumps as a result of a pump or turbine in the system.. True or False? 7) 5 points: The First Law of Thermodynamics states that the rate of change of energy within the system is equal to the net rate of heat added to the system plus the net rate of work done on the system. True or False? 8) 5 points: The drag on a sphere is dominated by skin friction drag while the drag on a streamlined body is dominated by pressure drag. True or False? 9) 5 points: The two types of drag acting on a body in a flowing fluid areform drag and pressure drag. True or false? 10)5 points: The Magnus effect describes the lift produced by a spinning body. Over-spin on a tennis ball causes the ball to drop faster than one with under-spin. True or false? 11)10 Points: Use of the Moody diagram for determining the resistance coefficient requires what two parameters? 12)10 Points: Total head loss in a system is the sum of what two types of losses?
