Q = Volume flow rate, = find, P= find E, the velocity of approach factor, can be calculated with E = 1 / sqrt(1-B^4) E = 1 1-B4 requires knowledge of the product CE. The beta ratio is = do/d1 Then, the Reynolds number needs to be calculated: 4Q Red1 Where, v is the fluid kinematic viscosity And d1 is the circular pipes diameter. PROBLEM 3: An in-line flow nozzle is to be used to measure the flow of ethyl alcohol (v = 1.52 x 106 m/s; p = 789 kg/m) through a 50 mm diameter pipe inline. The nozzle diameter is 28 mm, and the pressure drop across the nozzle is 4,000 Pa. a. Determine the volumetric flow rate. b. Determine the average velocity of the fluid. c. Determine the mass flow rate.
