QUESTION 5 a) Prove that the net external force acting on a moving fluid which undergoes a change in velocity is given by F =pQAv. (CO1-PO1)(C2) (5 marks) b) Figure Q5(b) shows water being discharged from the 50-mm-diameter nozzle of a fire hose at 0.015 m/s. The flow strikes the fixed surface such that 3/4 flows along B, while the remaining 1/4 flows along C. Compute the magnitude and show the direction of the resultant force that acts on the surface. (CO2-PO2)(C5) (10 marks) A 45% 50 mm Vo B 60 C
