Question

A horizontal pipe carries a smoothly flowing liquid of density of 1270 kg/mº. At Locations 1 and 2 along the pipe, the diameters are di = 6.05 cm and d2 = 3.51 cm, respectively. Is the flow speed at Location 2 higher or lower than the flow speed at Location 1? Location 1 Location 2 d2 higher cannot tell from the data O lower The flow speed at Location 1 is 1.31 m/s. What is the pressure difference AP between Location 2 and Location 1 (including its sign)? Ignore viscosity. AP= pa Is the pressure at Location 2 higher or lower than the pressure at Location 1? higher lower cannot tell O

Answer 1

density of Fluid (8) = 1270 kg / m3. die G.05cm, reaclius Crabe 4. - 0.03025 m de = 3.51cm, recol ius cry) - 42 - 351 0.01755m area of cross-sections Coy) - 4142 2.876X163 m2 area of creoss-section ca)= arc = 9.68608 x104m2 The flow speed at location is higher. Because acccorceling to equation of continuity air, = Q V2 ayaz Vi= 131 M/S OUVI - 2.876X103 x 1.31 9.68008 x 10 4 = 3.89 208 m/s. According to Bernoulli's Principle, AP= PR - P₂ = 25cvp-V, 2) 270 (13.43215) op = 8529.415201 Pa. & Pressure at & is lowere because AP = tv PITP. & Please rate Thank clear you!
