As shown in the figure, the pipe is supported at point A and is connected to the system where points 1 and 2 are measured. The fluid is incompressible. a. Determine the expression for the moment exerted at point A. b. Determine the value of the moment exerted at point A. If D1=D2=3 in, P1=100 Lb-f/in2 gage, P2=80 Lb-f/in2 gage, =1000 kg/m3, v1=40 ft/s, h1=2 in, h2= 10 in.
