Air flows at the rate of 1.5 m³/s through a horizontal pipe with a gradually reducing cross- section as shown in the figure. The two cross- sections of the pipe have diameters of 400 mm and 200 mm. Take the air density as 1.2 kg/m and and assume inviscid incompressible flow. The change in pressure (p2 - P₁) (in kPa) between sections 1 and 2 is Air Flow 1.5 m³/s 1 400 mm ↓ 200 mm
8-62 A horizontal pipe has an abrupt expansion from D₁ = 8 cm to D₂ 16 cm. The water velocity in the smaller section is 10 m/s and the flow is turbulent. The pressure in the smaller section is P₁ = 410 kPa. Taking the kinetic energy correction factor to be 1.06 at both the inlet and the outlet, determine the downstream pressure P2, and estimate the error that would have occurred if Bernoulli's equation had been used.
