a. Estimate the expansion factor in measuring the flow of Oz at 16 C through a 100 mm i.d. pipe using a square edged orifice plate. The upstream pressure is 6.9 bar abs, and the downstream pressure is 3.6 bar abs. The orifice diameter is 50 mm. Roz = 260 J/kg-K. b. Determine the permanent pressure loss caused by the orifice. 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 = d0/d1 Then, the Reynolds number needs to be calculated: 4Q Red1 * d * v Where, v is the fluid kinematic viscosity And d1 is the circular pipes diameter. a.
