f) Determine the diameter of the duct at B given that flow condition of d) and a pressure in B of PB = 7.65 kPa. If you could not work out the flowrate in d), use Q = 0.03 m. [5 marks] Salt water is pumped out of a ship hull through the pipe bend and nozzle shown in Figure 2. The engineer who operates the pump needs to use simple measurements to evaluate the flow rate. hw de Ship hull Salt water hc A d. Figure 2: Pipe bend and nozzle, drawing not to scale. The flow exits at C which is hw = 6m below the waterline. The pipe centreline at point C is hc 1m above point A. The internal radii of the pipe at A and C are TA dc = 0.035 m. The specific gravity of salt water is SG = 1.03. Work final answers to three significant digits, use g = 9.81. 0.05 m, TC = a) To compute the flow rate, the engineer can only measure the pressure in A. She also has only access to the same methods as taught in this class. What are the two largest errors that the engineer has to be aware of? Would those errors lead to an over- or underestimation of the flow rate? [4 marks] b) The engineer is asked to run a flow rate of Q = 0.02 m through the bend. Determine the %3! velocities in A and C. [3 marks) c) For the same flowrate as in b), calculate the gauge pressure at location A if frictional losses are assumed to be negligible. [5 marks] d) The pressure at A is changed to pa = 10 kPa. Determine the flow rate. [5 marks] e) The ship takes on more cargo. The engineer is told to run the same flow rate as in b) and she adjusts the pump to obtain the same pressure as in c). Will the flowrate be higher, the same, or lower? Explain your answer. [3 marks]
