Question 22
XE-BNAT2 marksNeeds review
An orifice plate is used to measure flow rate of air (density = 1.23 kg/m³) in a duct of 250 mm diameter as shown in figure. The volume flow rate is 1 m³/s. Flow at sections 1 and 3 are uniform and section 2 is located at vena contracta. The diameter ratio, D_t/D_1, is 0.66. The flow area at vena contracta, A_2 = 0.65A_t, where A_t is area of the orifice. The pressure difference between locations 2 and 3 in N/m² is __________.
