A device for measuring liquid viscosity is shown in Fig. P3.177. With the parameters (, L, H, d) known, the flow rate Q is measured and the viscosity calculated, assuming a laminar-flow pipe loss from Chap. 6, hf Heat transfer and all other losses are negligible. (a) Derive a formula for the viscosity µ of the fluid. (b) Calculate µ for the case d =2 mm, = 800 kg/m3 , L= 95 cm, H =30 cm, and Q =760 cm3 /h. (c) What is your guess of the fluid in part (b)? (d) Verify that the Reynolds number Red is less than 2000 (laminar pipe flow).
