Q3: The 6-cm-diameter pipe as shown in Figure H.I contains glycerin (p = 1260 %3D kg/m', u= 1.49 kg/m s) flowing at a rate of 6 m'/h. Verify that the flow is laminar. For the pressure measurements shown, is the flow up or down? What is the indicated head loss for these pressures? Answer: Head loss 25 m 3.7 atm B 2.1 atm 12 m Figure: H.1

Water flows from Reservoir A to Reservoir B. The pipe diameter D is 1 m, and the pipe length L is 300 m. H= 16 m, h = 2 m, and the pipe head loss is given by h₁ = 0.01), where U is the velocity in the pipe. In your solutions consider the head loss at the pipe outlet to be ( U² 2g (a) what is the discharge in the pipe? (b) What is the pressure at point P halfway between the two reservoirs?
