Situation Figure P2, below, shows a simple flow system used for steady flow tests with liquids. It consists of a constant head tank connected to a pipe. The pressure gauge is connected at a point where the flow is fully developed; the test section is the pipe segment between the gauge and the discharge. The liquid discharges into open air. The following information was available for a given test: u = 25 [cP]; p = 1.9 [kg/L); D= 4.1 [mm]; L = 5.7 [m]; (07) = 3.7 [m/s]; Patm = 740 [mm Hg] Pressure gauge L Internal diameter, D Requirements: Please, answer or do the following in the specified units when appropriate: (a) Convert... ... viscosity: 0.025 [Pars] ... density: 1900 [kg/m) (b) Reynolds number: 1152.9 Was the flow regime laminar? yes (c) The pressure drop in the test section was: 905.6 * [kPa] (d) The gauge reading (with the appropriate sign) was: X (psig]
